JA: Let's start with questions Jeanne had.
Jeanne: We had some new SC 4.9.9 to 4.9.13. We need some titles for
these.
JA Proposes scale viewport for 4.9.11
Group discussing if this is all media or not.
GL: Options are move some out or come up with better name.
... Would it make sense to separate into one based on media and one
that isn't.
JA: Do we just say scale playback viewport?
<scribe> ACTION: JA to update title of 4.9.11 to scale playback
viewport [recorded in
[13]http://www.w3.org/2010/02/25-ua-minutes.html#action01]
<trackbot> Created ACTION-300 - Update title of 4.9.11 to scale
playback viewport [on Jim Allan - due 2010-03-04].
/me how do I assign to someone else, just assigned to the wrong
person.
<jeanne> new version with todays edits:

Action 300 really belongs on JS.
<trackbot> Sorry, couldn't find user - 300
Group discussion what is really meant by scaling and sizing.
MH: Want to be able to limit keeping and not lose aspect ratio.
That's limit clipping.
JA: I've seen players that let you double size of player and media
still stays within aspect ratio.
GL: Do we want the user to be able to make the actual video larger
but not at the cost of losing something else e.g. cropping or
scaling that loses the aspect ratio.
<mhakkinen> User has the ability to adjust the size of the content
within the playback viewport, with the option to preserve aspect
ratio and to adjust the size of the playback viewport to avoid
cropping.
<mhakkinen> User has the ability to adjust the size of the content
within the playback viewport, with the option to preserve aspect
ratio and to adjust the size of the playback viewport to avoid
cropping, within the limits of the containing viewport.
JS: What level are we talking about?
More discussion about scaling, size. Some video may only be scalable
by certain sizes.
GL: Do we think it is acceptable to not allow scaling to the full
size of the viewport?
<greg> Kim suggested "User has the ability to adjust the size of the
content up to the full height or width of the containing viewport,
with the option to preserve aspect ratio and to adjust the size of
the playback viewport to avoid cropping, within the limits of the
containing viewport."
JS: I'm not sure at AA we need an option to preserve aspect ratio as
an option.
JA: Default is that aspect ratio is always preserved. User can turn
it off.
JS: This means developer has to add ability to turn this ability of
preservation off.
More discussion about preservation of aspect ratio and what option
implies.
<mhakkinen> User has the ability to adjust the size of the content
up to the full height or width of the containing viewport, with the
ability to preserve aspect ratio and to adjust the size of the
playback viewport to avoid cropping, within the limits of the
containing viewport
<jeanne> issue: Review the document for consistency of the use of
option: option, ability, by default, on/off, or always.
<trackbot> Created ISSUE-65 - Review the document for consistency of
the use of option: option, ability, by default, on/off, or always. ;
please complete additional details at
[15]http://www.w3.org/WAI/UA/tracker/issues/65/edit .
[15] http://www.w3.org/WAI/UA/tracker/issues/65/edit
Discussion of what option is about continues.
G: Makes point about options that are on by default and uses
keyboard option needinGL: to be on by default or keyboard user would
be stuck.
<jeanne> kim: the use of "by default should be rarely used so as not
to limit developer unnecessarily and should only be used when the
non default option would prevent accessibility.
<jallan> GL: use "user has the ability" vs "user has the option"
throughout the document
GL: If we really want the ability to turn off/on important options
we should use on/off explicitedly.
Group returning to actual 4.9.11 SC.
<mhakkinen> User has the ability to adjust the size of the
time-based media up to the full height or width of the containing
viewport, with the ability to preserve aspect ratio and to adjust
the size of the playback viewport to avoid cropping, within the
limits of the containing viewport
GL: We don't restrict this to time based media right now. If this is
what we mean we should be explicit.
<jallan> techniques: if the codec does not support unlimited
resizing, this will limit the users ability for resizing
Group talking about issues that arise from exceptions and how to
handle. For example audio.
<jallan> MH: scaling limit imposed by the media
<mhakkinen> User has the ability to adjust the size of the
time-based media up to the full height or width of the containing
viewport, with the ability to preserve aspect ratio and to adjust
the size of the playback viewport to avoid cropping, within the
limits of the containing viewport, and by any scaling limitations
imposed by the media itself.
<mhakkinen> User has the ability to adjust the size of the
time-based media up to the full height or width of the containing
viewport, with the ability to preserve aspect ratio and to adjust
the size of the playback viewport to avoid cropping, within the

imposed by the media itself.

Group now looking for title on 4.9.12.
↑4.9.12↑ TITLE NEEDED↑. User has ability to scale and position
alternative media tracks independent of base video. (Level AAA)↑
Group revisits examples of this like a presentation at csun that
scrolled 5 lines of captioning.
Title for 4.9.12 is scale and position of alternative media tracks.
↑4.9.13↑ TITLE NEEDED↑. User has ability to control the contrast and
brightness of the content within the playback viewport. ↑
GL Need levels on a couple of these.
<jallan> University of Toronto had working examples 10 years ago.
Geoff Freed and Larry Goldberg session at CSUN 2 years ago showed
many examples caption in different locations, but not the user could
disconnect and move where needed.
<jallan> discussion of contrast/brightness of only video vs all
media. what should the recommended range be.
<jallan> ACTION: jallan to find appropriate range of
contrast/brighness adjustment [recorded in
[17]http://www.w3.org/2010/02/25-ua-minutes.html#action02]
<trackbot> Created ACTION-301 - Find appropriate range of
contrast/brighness adjustment [on Jim Allan - due 2010-03-04].
<jeanne> ACTION: jeanne to put in Status notes that the group needs
expertise in contrast bright adjustment range for video for low
vision [recorded in

low vision [on Jeanne Spellman - due 2010-03-04].
<jallan> new title: 4.9.13 adjust playback contrast and brightness
<jallan> need to be consistent...do we use time-based media or
playback viewport.
<jallan> GL: need to define playback viewport
Group talking about if playback is really a short hand to time based
media.
Looking at definitions.
<jallan> definition synchronized media
<jallan> audio or video synchronized with another format for
presenting information and/or with time-based interactive
components, unless the media is a media alternative for text that is
clearly labeled as such

4.8 Proposal
<jeanne> 4.8.1 Configure Position: For graphical user agent user
interfaces with toolbars, the user can add, remove and configure the
position of user agent user interface controls on those toolbars
from a pre-defined set of controls. (Level AAA)
<jeanne> When the user has the ability to arrange interface
controls, the interface becomes flexible enough to meet the needs of
people with disabilities, including cognitive disabilities.
<jeanne> Example:
<jeanne> A user with cognitive disabilities can create a toolbar
that contains only the functions they need without other components
that could distract. The user agent provides a dialog box with a
list of available components that users can choose to add or remove
from a toolbar, and organize in any order. The dialog box and
controls are programmatically available to assistive technology and
can be operated by keyboard via cut and paste.
<jeanne> 4.8.2 Restore Default Toolbars: The user can restore the
default toolbar configuration. (Level AAA)
<jeanne> Error recovery is an important support for users with
cognitive disabilities and for users who may not be able to see
changes to the interface. A user making changes to a toolbar
configuration needs a simple ability to reset the toolbar to the
default configuration and start again.
<jeanne> Example:
<jeanne> The dialog box for creating toolbar has a keyboard
accessible button at the bottom labeled "Reset".
4.6.2: Find Direction:
Intent:
Searching in any direction from the current point of focus allows
for maximum flexibility in allowing the user to easily locate the
text used in the search.
Example:
A user has been reading through a web page and wants to quickly
locate a phrase previously read. When opening the browser’s page
search feature, the user has options to search forward and backward
from the current location. If the search reaches an endpoint in the
document, the user is notified that the search has wrapped around,
such as with an alert box or other indication.
Resources:
4.6.3 Match Found
Intent:
The user should be alerted of a successful search and be able to
easily view the successful search and related text.
Example:
When a successful search happens within a document, the viewport
scrolls so the user can read at least the surrounding sentence. The
user can also quickly initiate a search for the same text if the
match in question is not the desired instance of the found text.
Resources:
<jallan> GL: enhance 4.6.2 greatly reduce amount of reading they
need to read through to find the information they need. Improve
navigation efficiency for people with dexterity issues.
<jallan> ... Improve navigation efficiency which is expecially
important for people with dexterity issues (telephone based
browsing, speech input users, etc.). Or reducing the number of
utterances for people using speech input
<jallan> dexterity issues, every keystroke is time consuming,
tiring, or painful

<jallan> 4.6.3 Match Found Intent: The user should be alerted of a
successful search and be able to easily view the successful search
and related text. Example: When a successful search happens within a
document, the viewport scrolls so the user can read at least the
surrounding sentence. The user can also quickly initiate a search
for the same text if the match in question is not the desired...
<jallan> ...instance of the found text.
<greg> For intent of 4.6.2: It is important to provide explicit
feedback when a search reaches the end of the document and starts
again from the beginning, or vice versa, so that a user who cannot
easily see scroll bars and other passive feedback mechanisms does
not end up searching through the document over and over again
without realizing it.

4.6
<greg> Re Simon's 4.6.1, "search within rendered content for text
and text alternatives" makes it sound like you're search FOR rather
than WITHIN the text.
<jallan> 4.6.1 Find: The user can perform a search within rendered
content (e.g., not hidden with a style) within text and text
alternatives, for any sequence of characters from the document
character set. (Level A)
<mhakkinen> 4.6.1 Find: The user can perform a search within
rendered content (e.g., not hidden with a style), including text
alternatives, for any sequence of characters from the document
character set. (Level A)
this seems good.
<jallan> Resolution: > 4.6.1 Find: The user can perform a search
within rendered content (e.g., not hidden with a style), including
text alternatives, for any sequence of characters from the document
character set. (Level A)
<greg> Re 4.6.2 "from any selected or focused location", does that
mean that when selection and focus are separated, the user has the
choice of which location to search from?
<jallan> discussing 4.6.2. search from focus or selection.
<jallan> KP: also an issue for keyboard vs mouse, easy to change
focus with mouse
<sharper> Find Direction: The user has the option of searching
forward or
<sharper> backward within any selected or focused location in
content. The user will
<sharper> be notified of changes in search direction; and when the
search reaches
<sharper> the upper or lower extent of the content based on the
search direction.
<sharper> (Level A)
<jallan> > Find Direction: The user has the option of searching
forward or backward from focused location in content or within any
selected content. The user will be notified of changes in search
direction; and when the search reaches the upper or lower extent of
the content based on the search direction. (Level A)
<jallan> Find Direction: The user has the option of searching
forward or backward from the focused location in content. The user
will be notified of changes in search direction; and when the search
reaches the upper or lower extent of the content based on the search
direction. (Level A)
<jallan> AAA search within selection- lots of mentions of a
particular word, but want to limit the search area of finding the
particular word.
<jallan> for instance in a blog. in word processing very useful.
<jallan> JS protest inclusion as AAA
<jallan> KF, KP +1
<jallan> discussion of use case
<jallan> SH: google docs, might have this feature.
<jallan> KF: conformance, hard to build a use case for this. AAA
should not be a wish list.
<jallan> KP: would be useful in google doc, but may not be as useful
in web pages.
<jallan> SH: protest. we should include this.
<jallan> ... can we put this in the document and as the reviewers at
the next draft for feedback.
<greg> Since there is debate over whether searching within a
selection should be an SC, a compromise is to make it a best
practice discussed in the Implementation document, rather than an
actual SC.
<jallan> For implementation.. It is recommended that the user also
has the ability to search forward or
<jallan> backward within any selected content. @@needs some
explanation. how to keep searching within the selected content
<jallan> discussing 4.6.3
<jallan> GL: "Or, if the caret has been moved, from its new
location." seems to overlap with 4.6.1
<jallan> JA: +1
<jallan> KP: but should be included in the implementation.
<jallan> 4.6.3 Match Found: When there is a match, it is
highlighted, and the viewport moves so that the matched text content
is at least partially within it. The user can search for the next
instance of the text from the location of the match.

<jallan> KF: item 5. what do we want people to list. the examples
confuse me
<jallan> JS: eg. mathml, someone would want to know that it is
accessibly supported.
<jallan> KF: but we have no requirements for mathml
<jallan> KP: it is useful to have a list so someone can look up
<jallan> KF: so IEx is level A compliant with uaag20. mathml has
nothing to do with that.
<jallan> GL: fine, but user may need to know about mathml
<jallan> KF: this is a nice to have. not required.
<jallan> KF: browser with no search. conformance claim, I would say
I comply with 4.6 because I include the search plugin for the cool
browser
<jallan> JS: this is an opportunity to meet some requirements you
might otherwise not meet
<jallan> ... eg. ability to resize video. some format would not meet
the requirements. so you can say I conform but I exclude formatxx.
<jallan> KF: need better examples.
<jallan> KF: Flash
<jallan> GL: list of 2 things, things you support in an accessible
way, and things that you support but are not accessible.
<jallan> list might include:
<jallan> ... html (versions)
<jallan> ... css (versions)
<jallan> ... video/audio codecs included with install
<jallan> ... plugins (own or 3rd party - must be specific) that are
needed to meet specific SC
/me Do we want this scribed and who wants to scribe?
<jallan> discussion of conformance
<jallan> discussion of creating a tool for folks to submit
conformance claims.
<jallan> ...who will monitor and maintain and verify
<jallan> ... do we want a formal or informal claim of compliance.
WCAG has formal, ATAG has informal
<jallan> KF: do most specs have a conformance section,
<jallan> JS: all WAI documents have them. ATAG says posting
conformance to the web is optional, because there are so many
authoring tools. UAAG has a narrower scope
<jallan> JS: is posting a claim a requirement for conformance
<jallan> ... claim on a collection of technologies.
<jallan> ... is included, exclude technologies part of conformance
<jeanne> scribe:mhakkinen
JA: i think posting a claim is a good thing, browsers to meet level
A will have to do that. There are some things they can exclude.
... my concern, is that if UA doesn't do TTS, does it then exclude
the level A's related to TTS?
JS: If you don't have TTS, then you say that with JAWS it is.
GL: Don't want UA claiming UAAG conformance but excluding half of
UAAG?

a kiosk) that does not support AT
<kford> conformance claim. The user agent is not required to meet
the

draft.
<kford> requirements of UAAG 2.0 during the production of the web
content
<kford> A declaration that the success criterion is not applicable
and a
<kford> rationale for why not.
<jeanne> ACTION: JS to put the Conformance proposal into the
document for further discussion. [recorded in
[34]http://www.w3.org/2010/02/25-ua-minutes.html#action12]
<trackbot> Created ACTION-307 - Put the Conformance proposal into
the document for further discussion. [on Jeanne Spellman - due
2010-03-04].
<greg> I'm concerned that, while the Conformance Claims section
allows listing SC that are inapplicable to the UA, the Conformance
Requirements section does not provide for any exceptions, including
on the grounds of inapplicability (e.g. stand-along systems that
don't allow addiiton of assistive technology).
<greg> Therefore we're discussing modifying Conformance Requirements
to include wording about exceptions where SC are inapplicable.
<greg> See ISO 9241-171 for example wording: Conformance with this
part of ISO 9241 is achieved by satisfying all the applicable
requirements and by the provision of a systematic list of all the
recommendations that have been satisfied. Any requirements that have
been determined not to be applicable shall also be listed, together
with a statement of the reasons why they are not applicable.
JA: A UA could say we don't do TTS and the AT vendor could claim
conformance, when there SR is used with the UA.
KF: what does saying "it works with JAWS" really mean?
<greg> Conformance claim would ideally distinguish whether
compliance with a success criterion is available (a) by default, (b)
with configuration changes that can be made through the product or
the platform, (c) with separate software (e.g. Firefox add-in).

[35] http://www.w3.org/WAI/UA/impl-pr2/evaluations/eval_win_ie6.html
JA: example of IE6 eval with UAAG1 posted
GL: distinguish between external sw/plugins you pay for or are free.
KF: should not ref cost. May not be as efficient.
<greg> Users can also benefit from a report on compliance with
constellations or sets of success criteria, which could help them
distinguish whether it was accessible to people with their needs
(e.g. great on keyboard, even if lousy on screen reader access).

<jeanne> ACTION: Jeanne to put proposals for Implementing Principle
4 for next week's survey. [recorded in
[36]http://www.w3.org/2010/02/25-ua-minutes.html#action13]
<trackbot> Created ACTION-308 - Put proposals for Implementing
Principle 4 for next week's survey. [on Jeanne Spellman - due
2010-03-04].
Guideline 3 Implementations
pairing up and picking numbers
<kford> 3.8.1-3 override of speech characteristics
<kford> Intent:
<kford> The objective of these success criteria is to allow the user
to customize the specified speech characteristics to settings that
aare appropriate to the way the user needs to consume the audio
information. Users may need to increase the volume to a level within
their range of perception for example. Users may also wish to
increase the rate of synthesized speech because they can
understand...
<kford> ...it at a faster rate than the author-defined rate.
<kford> Example:
<kford> A telephone based web browser starts reading back a web
page. The user can press a key to increase the rate at which the
information is read back. Similarly, the user may be using this
telephone browser inaa noisy environment such as a crowded subway.
With a key press the user can quickly increase the volume of the
speech being heard.

information is read back. Similarly, the user may be using this
telephone browser inaa noisy environment such as a crowded subway.
With a key press the user can quickly increase the volume of the
speech being heard.
Intent of Success Criterion 3.7.1:
User agents can render audio from a variety sources, and in some
cases, multiple audio tracks may be present
on a single page. Screen reader or self voicing browser users may
encounter content where the presentation
volume of an audio track makes it difficult to hear the text to
speech synthesis of their screen reader or browser.
Users should be able to globally set the volume of audio track
globally, rather than having
to adjust the volume of each audio track player.
Examples of Success Criterion 3.7.1:
A user agent provides a master audio volume control that applies to
all audio tracks rendered from content. The user may
define a default volume level through a preferences dialog that is
retained across browsing sessions.
3.7.1 Global Volume: The user can globally set volume of all audio
tracks it renders (including a "mute" setting) through available
operating environment mechanisms. (Level A)
Intent of Success Criterion 3.7.1:
User agents can render audio tracks from a variety sources, and in
some cases, multiple audio tracks may be present
on a single page. User of a screen reader or self voicing browser
user may encounter content where the presentation
volume of an audio track makes it difficult to hear the text to
speech synthesis of their screen reader or browser.
Users should be able to globally set the volume of audio track,
rather than having
to adjust the volume of each audio track being played.
Examples of Success Criterion 3.7.1:
A user agent provides a master audio volume control that applies to
all audio tracks rendered from content. The user may
define a default volume level through a preferences dialog that is
retained across browsing sessions.
revised 3.7.1 follows:
Guideline 3.7 Provide volume configuration.
3.7.1 Global Volume: The user can globally set volume of all audio
tracks it renders (including a "mute" setting) through available
operating environment mechanisms. (Level A)
Intent of Success Criterion 3.7.1:
User agents can render audio tracks from a variety sources, and in
some cases, multiple audio tracks may be present on a single page.
User of a screen reader or self voicing browser user may encounter
content where the presentation volume of an audio track makes it
difficult to hear the text to speech synthesis of their screen
reader or browser. Users should be able to globally set the volume
of audio track, rather than having to adjust the volume of
each audio track being played.
Examples of Success Criterion 3.7.1:
A user agent provides a master audio volume control that applies to
all audio tracks rendered from content. The user may define a
default volume level through a preferences dialog that is retained
across browsing sessions.
A user encounters a page with two advertisments and one video which
began playback on page load complete. A global mute command in the
user agent allows the user to immediately silences the playing audio
tracks, while leaving their screen reader's text to speech
synthesizer volume at their preferred level.
3.7.1 Global Volume: The user can globally set volume of all audio
tracks it renders (including a "mute" setting) through available
operating environment mechanisms. (Level A)
Intent of Success Criterion 3.7.1:
User agents can render audio tracks from a variety sources, and in
some cases, multiple audio tracks may be present on a single page.
Users should be able to globally set the volume of audio track,
rather than having to adjust the volume of each audio track being
played.
Examples of Success Criterion 3.7.1:
An operating system provides a master audio volume control that
applies to all audio tracks rendered within the environment,
including the user agent. The user may define a default volume level
through a preferences dialog that is retained across sessions.
A user encounters a page with two advertisments and one video which
began playback on page load complete. A global mute command,
supported via a mute key on the user's keyboard, allows the user to
immediately silence the playing audio tracks.
3.7.2 Speech Volume: The user agent allows the user to adjust the
volume of all audio tracks it renders, independent or relative to
the volume level at the operating environment.
Intent of Success Criterion 3.7.2:
Users of a screen reader or self voicing browser may encounter
content where the presentation volume of an audio track makes it
difficult to hear the text to speech synthesis of their screen
reader or browser. Users should be able to set the individual volume
of audio tracks rendered by the user agent, including text to speech
synthesis, independent of the operating environment's volume
settings.
Examples of Success Criterion 3.7.2:
A self-voicing user agent provides separate audio volume controls
the speech synthesizer and audio tracks rendered from content. The
user may define default volume levels through a preferences dialog
that is retained across browsing sessions.
A user encounters a page a video which begins playback on page load
complete. A volume control for rendered audio tracks allows the user
to immediately silence the audio track, while leaving their screen
reader's text to speech synthesizer volume at their preferred level.
my nokia linux phone just rebooted
<kford> I'll call you back.
<kford> But is this burning all your cell minutes, do you want me to
use the regular line?
it is still booting.
no, you can use this line, I have a good plan.
<kford> I was just saying that in your second sentence it needs to
be audio tracks or an audio track.
you can try calling now
<kford> 3.8.4 speech features
<kford> Intent:
<kford> Synthetic speech can be difficult to understand at times.
The purpose of this criteria is to offer controls that allow the
user to clarify items that tend to need clarification when using
synthetic speech.
<kford> Example:
<kford> The speech synthesizer incorrectly pronounces the last name
of a user. A dictionary allows the user to enter a spelling of the
name that produces the correct pronunciation from the synthetic
speech.
<kford> A speech synthesizer is repeating a phone number. The user
wishes to easily copy this number so switches to a mode where each
digit is spoken as a unique word e.g. five, five, five and so on.
<kford> 3.8.4 speech features
<kford> Intent:
<kford> The synthetic speech presentation of text can be difficult
to understand at times. Success criteria here are aimed at giving
the user the ability to adjust the way in which the speech
synthesizer presents text to improve understandability.

Intent of Success Criterion 3.13.1:
Links within Web content can result in actions that may change
context, open new browser windows, or result in downloads of content
or media that the user cannot view. The intent of this criterion is
to provide sufficient information to users identify the purpose of a
link, the type of content to be linked to, and whether the content
will appear within the current viewport or open in a new viewport.
Examples of Success Criterion 3.13.1:
A user encounters a link on a product support Web site that
identifies that more information is available regarding the use of a
product. The link content indicates the information is in a document
format that is not familiar to the user, and that it will be opened
in a new browser Window. The user finds a second link indicating
that the same information is available as an HTML page, and will be
viewed in the current browser window.
Revised 3.13.1:
Guideline 3.13 Provide link information.
3.13.1 Basic Link Information: The following information is provided
for each link (Level A):
(a) link element content,
(b) link title,
(c) technology type: of the linked Web resource,
(d) internal/external: whether the link is internal to the resource
(e.g., the link is to a target in the same Web page),
(e) new viewport: whether the author has specified that the resource
will open in a new viewport.
Intent of Success Criterion 3.13.1:
Links within Web content can result in actions that may change
context, open new browser windows, or result in downloads of content
or media that the user cannot view. The intent of this criterion is
to provide sufficient information so that users may identify the
purpose of a link, the type of content to be linked to, and whether
the content will appear within the current viewport or open in a new
viewport.
Examples of Success Criterion 3.13.1:
A user encounters a link on a product support Web site that
identifies that more information is available regarding the use of a
product. The link content indicates the information is in a document
format that is not familiar to the user, and that it will be opened
in a new browser Window. The user finds a second link indicating
that the same information is available as an HTML page, and will be
viewed in the current browser window.
<kford> 3.9 stylesheets
<kford> Intent:
<kford> CSS stylesheets allow for extensive customization of the
rendering of web content. Such customization is frequently used to
make web content accessible to a wide range of user needs. These
success criteria ensure that users of web browsers can fully take
advantage of the stylesheets offered by web authors of that the
users have created.
<kford> Example:
<kford> A user finds yellow text on a black background easiest to
read. When a web site is loaded, the user agent alerts the user that
the web author has created several stylesheets for the web site. The
user selects a stylesheet named yellow on black from a menu in the
user agent listing all available stylesheets. The web content is
then rendered using this stylesheet.
<kford> On a shared computer a web site is rendered with black text
on a white background that is normally in full color. The user agent
notifies the user that a user-defined stylesheet has been applied to
the web page and the user easily disables this stylesheet. The web
site is now rendered in full color.
Examples of Success Criterion 3.13.2:
Users may not readily determine, from link content or context, that
the target page has already been visited. A user agent may indicate
through color, or in the case of a self-voicing browser, through a
spoken announcement, that a link has been previously visited.
A user is deciding whether to download the lite or full version of a
new browser plug-in. Because the user is on a mobile internet
connection, download time and cost is a significant concern. The
link to each download provides the size of the file, allowing the
user to decide which should be downloaded.
A student is searching for research articles in cell biology. An
article of interest provides and english summary on the author's Web
site, but the link to the full article indicates that the content is
in a language the student does not understand.
Intent of Success Criterion 3.13.2:
The intent of this criterion is to provide extended information that
allows users to determine whether a link should be selected, based
upon whether the link has been previously visited, by the size of
the content to be downloaded when the link is selected, or by the
language of the linked content.
