Open Actions were reviewed


1. A week from today (April 27th, 4:00 Eastern there will be special joint 
GL UA call related to markup for navigation - to develop consensus on 
techniques for
marking up links for navigation . Hopefully results will be clear 
guidelines for inclusion in the techniques UA and GL (Wendy has sent 
proposal re: using MAP for
navigation bars).

2. If UA group does not get through open issue there will be an extra 
telecon on the 25th Discussion

PR#273: Checkpoint 10.9: Why graphical controls only?


JG: This is a priority 3. Currently the doc only talks about graphical 

Reviewing: Ian's proposal

What would be the minimal requirement to satisfy?

JG: Jon proposed "allow user

GR: Could we change the graphic . For example, use the tool tip to replace 
the graphic.

AL: would like to have option to order things listed in a menu, 
particularly useful when accessing auditorially (like phone menus)

DB: sounds like it is going beyond rearranging graphics

JG: Original purpose was for individuals with small range of motion, could 
cluster controls in a area together. During review, other reasons for 
elements were brought up, for example rearranging menu items

HR: Do we consider the menu to be a control?

JA: Does that include min, max...we could end up rearranging whole screen?

JG: min requirement may just be changing the position or number

AL: Yes, I wording does answer the reviewers comments. The re-wording is ok.

Proposed Wording For graphical user interfaces, allow the user to configure 
the arrangement of user interface controls.

Resolved: Accept IJ's rewording of Tuesday 4/18/00

JG: Allow the user to change the number, position and function of the 
buttons on available tool bars??

DB: does that mean change the function of a button

AL: Allow the user to change the number, position and selection of the 
buttons on available tool bars??

DB: we don't want to require a tool bar

Allow the user to change which functions and the positions of the functions 
on available tool bars

Note to Ian - We want wording to the effect - allow user to choose which 
function/buttons show up where on the toolbar.


Al: Users of speech won't know about hot keys until they get to in a 
sequential manner.

JG: May also be an issue for individuals with the cognitive disabilities

JG: seems like order and number could be important for individuals who are 
blind and who cognitive disabilities

JG: We need to specify a minimum requirements so everyone doesn't interpret 
this differently

JG: What about - Allow the user to change the order and remove and add of 
items in pull down menus.

KB: I would want a restore feature if we are going to allow people to 
remove menu items.

JG Should we add - Also user to restore default configuration.

GR: Would restoring defaults be covered in our profile checkpoint.

JG: Allow the user to restore default the menu and toolbar settings (cross 
reference checkpoint 10.7)

DB: does this mean default for menus and toolbars together or just one menu

AL: point of cross reference - if there is a profile mechanism user should 
be able to restore to factory defaults - Users would need restore 
application defaults

Summary - 3 requirements
1. Allow the user to change which functions and the positions of the 
functions on available tool bars Note to Ian - We want wording to the 
effect - allow user to
choose which function/buttons show up where on the toolbar.
2. Allow the user to change the order and remove and add of items in pull 
down menus.
3. Allow the user to restore default the menu and toolbar settings (cross 
reference checkpoint 10.7)

PR#271: Checkpoint 4.7: Change to P2 since arbitrary repositioning not a 


JG: At f2f - key issues
1) alt equiv is not obscured ,
2) video/image can be viewed simultaneously with the transcript

Notes from Ian UA doesn't have to allow for configuring - if information is 
not obscured

AL: This is p1 because of the need to support simultaneously magnification 
and captions. Not intent to always require arbitrary positioning, but some 
capability that makes simul mag and captions.

AL: Wording on not obscuring not the best way to answer the commenter's 
questions - want to make it clear - it is not arbitrary control.

JG: Good if we can express in functional needs, that is where obscure 
wording is helpful

AL: User has to have the choice - content may need to obscure other content 
- user should have reasonable control, if captions get so big they it has 
to blot out
video..want to leave control in hands of user - whether need to obscure or not

AL: minimum implementation under magnification - need to be able to place 

Action AL: Al will post to the list a discussion of this topic to show that 
we still need to work on wording

1)this is priority 1
2) we do need to allow user to choose whether info is obscured or not
3) functional requirements - how much configuration is needed.

PR#260: Guideline 1 checkpoint language unclear.


Review Ian's proposed new language


1.1 Ensure that every functionality available through the user interface is 
available through every input API implemented by the user agent. [Priority 1]

Note. This checkpoint does not require developers to implement all 
operating system input APIs, only to make the software accessible through 
those they do
implement. The device-independence required by this checkpoint applies to 
the functionalities described by the other checkpoints in this document (e.g.,
installation, documentation, user agent user interface configuration, 
etc.). This checkpoint does not require developers to reimplement the input 
associated with the keyboard, pointing device, voice, and other device APIs 
For example, developers are not required to implement text input through a 



Note. Developers should use APIs available at a higher level of abstraction 
than device APIs, provided that, in turn, these higher level APIs make use 
of the
standard device APIs for the operating system.



1.4 Implement the standard keyboard API of the operating system and ensure 
that every functionality available through the user interface is available 
through this
API. [Priority 1] Note. This checkpoint always applies on systems with a 
standard keyboard API. This checkpoint is an important special case of 
checkpoint 1.1.
Refer also to checkpoint 10.8


JG: I think we are clear that developers don't need to generate text 
through a mouse.

JG It is clear that if you implement voice input you should do it 
accessibly. Developers would probably want to make the whole thing voice 

AL: May run into this problem (voice control not working) during 
installation. What if installation doesn't support voice input.

JG: Gregory would installation be considered a separate program.

GR: I would consider installation part and partial of product.

*** Ian joined (yeah!)

IJ: There could be a boot strap problem. If you have to install voice 
component it could be a problem. If OS doesn't support voice, how do you 
install UA with

GR: Other example, screen reader installation is self voicing - installs a 
temporary module until actual program gets installed

JG: Let's move this to the list

IJ: any objections to incorporating.

Resolved: adopt Ian's proposal with incorporation of comments from the list.

PR#233: Checkpoint 7.6: What does "structure" mean here?


JG: Related to configure UA to navigate structure. Current min reqs 
proposal for 7.6 - says 1) allow user to sequentially navigate current 
through rendering in the
viewport human recognizable.....for example, header...... 2) if no 
structural defined use programmatic structure.... (see draft requirements doc)

IJ: Sounds like minimum is to use document object.

The DOM is limited to XML and HTML. Document objects can include scripts or 

Document Object - user agent's representation........ see Ian's proposed 

IJ: not clear in generic sense what is actually in the document object... 
the W3C DOM is specific, document object not

IJ: Structure - What it means is document object. It has structure, so 
minimal navigation.

JG: For example in HTML, would have a command that would allow you to 
highlight each element in the document tree.

JG: this would allow users to identify an element on the screen and know 
what that "chunk" represents. But some people have pointed out that there 
are human
understandable things (e.g. heading level 2 should be under level 2 etc)

IJ: For a lot of these checkpoints it is difficult to specify minimal 
requirements. Here is one where absolute min. req is navigation of 
everything in document object
in a particular viewport. We expect more and when there are conventions 
like for HTML, we expect more. We can say min is access to every element in 
the tree
and we can add suggestions for how to do it better.

IJ: If we express what we are thinking - structured navigation - does that 
help developers.

JG: we want to give people more guidance the we currently are on how to 
satisfy this checkpoint. The min. should be to provide the capabilities for 
more complex
navigation in the future. This may also be device specific.

IJ: When we say navigate - what are the navigation functions, so far we 
have forward serial navigation. We haven't talked about going up the tree 
and across

Action AG: Al will take an action to post to the list about structured 

HR. Does this DOM tree related to rendered content

IJ: no???

JG: just because something is in w3c DOM tree doesn't mean it is for human 
understanding. Just because you are navigating tree doesn't mean it is human
understandable. For real structured navigation, what better navigation. 
Actually want to go a step beyond the DOM. More beneficial once you can 

JG: Current minimum is navigating the document tree.

IJ: We do want to clarify the "more" we are looking for in this checkpoint. 
We decided to stay more general and flexible but we have had a bunch of 
ideas for
navigating (in techniques).

JG: not resolved until we hear from AL

IJ: can we take 2 minutes to hear from Gregory on DOm

GR: concern - we decided to make a forward looking document. Stepping back 
is more for ER group. There is a dependency between UA and PF to ensure that
PF is monitoring DOM work and playing a greater role in ensuring DOM 2 
addresses our concerns.

IJ: I think we chose to go with DOM2 because we liked what it had to offer. 
Dropping to DOM1 is more a strategic decision to get a document out. Few
documents are XML. I encourage us to drop to DOM1 and get the UA document 
out the door. For CSS, I could part with it in order to get this document out
and in the next round adopt CSS and events that suit us.

IJ: Still have the option to build in language that we "move up" to DOM2 
some time after it is out.

1. wait for DOM 2 to come out (4-6 months)
2) go back to DOM1 - already out, we can control our timing to 
recommendation, could incorporate DOM2 when desired
3) add contingency language - adopt DOM2 when available (we think we know 
what we will get)

Harvey- we'll have to go through another 3 months after DOM2 is out

IJ: Much content does not use namespace today. We should get document out now.
