AGENDA
------
a) Proposal to clarify checkpoint 2.9
http://lists.w3.org/Archives/Public/w3c-wai-ua/2001JanMar/0453
IJ: Note that, e.g., 3.7 is an important special case of 2.9.
But remember that 3.7 is about disorienting visual imagery, not
access to conditional content. You could satisfy 2.9 at the same
time as 3.7 by rendering "alt" instead of images.
IJ: I think that the solution of rendering alt instead of any images
is one solution to satisfying 2.3. Maybe some clarification is
required because when you satisfy through query, element-level control
is clear. Less clear when the global replacement solution is taken.
EH: I think it needs to be made clearer: depending on which option you
choose, the requirments change slightly.
IJ: I'm not sure that query mechanism works for 2.9. In the case
of specs where conditional content rendering is fully described, 2.9
still says "let me do the rendering globally, automatically."
CMN: WAI PF is starting to look at the question of expected renderings
of features. What we want is a functional rendering configuration.
IJ: I think there are some conditions that can't be simulated.
IJ: I think 2.9 looks like 2.3, but differences are:
- Global effect (not element-level control).
- Automatic
JG: It seems like 2.9 only applies in the query case.
IJ: Except that element-level control is possible to meet 2.3 and
that wouldn't work for 2.3.
Resolved:
- We agree that 2.9 is about automatic rendering, and applies
to all conditional content (element-level control is not required).
Action IJ: In next draft, clarify the relationship between 2.3 and 2.9.
b) I'd like to get confirmation of changes to the speech
characteristic checkpoints of the 19 March 2001 draft
(as announced:
http://lists.w3.org/Archives/Public/w3c-wai-ua/2001JanMar/0472)
/* Editorial note to Ian: 4.14 needs editorial fix, two notes need
to be one */
EH: The minimal requirement for 4.13 is not clear.
IJ: What piece is missing?
JG: 4.14 and 4.15 are about specific capabilities. These may not
exist in 4.13.
IJ: This needs to be made clearer: 4.14 is like 4.13 but imposes
particular characteristics. Your speech synthesizer has to support
these characteristics.
JG: The preset voices may be a way to change these parameters. Leave
the note.
Action IJ: Add "accent" to the list of "gender" and "age".
EH: Shouldn't the Note of 4.13 also include "pitch range" and
other more specific characteristics.
MQ: Some of the terms we use here (e.g., richness) I've not seen
defined in any synthesizer.
IJ: That's why we point to CSS2 for the description.
GR: Speech synthesizers do have a concept of richness. E.g.,
DoubleTalk LT has richness settings (e.g., echo chamber).
JG: I think the DecTalk also supports that parameter.
MQ: I think we need stronger definition of "richness".
CMN: I share Mickey's concern. It would be nice to copy the
glossary reference into our own glossary.
IJ: Three questions:
a) Do CSS2 terms meet our needs?
IJ: I note that CSS2 is a W3C Recommendation, which is a strong
stamp of approval.
b) How normative are they?
c) Editorial: Should we copy the terms in UAAG 1.0.
JG: From the Cambridge face-to-face, it was clear that one reason
we have 4.14 and 4.15 is for support for a system like CSS2. These
checkpoints are for designers choosing which speech technology to
include in their product. I don't think we need to do more to
define "richness".
GR: There is such a diversity of names among speech synthesizers,
I think it's valuable to use a common term such as "richness", which
is defined in CSS2.
Resolved:
- Use the CSS2 definitions as normative definitions.
- Include definitions in the UAAG 1.0 Glossary.
c) Checkpoint 9.1: Delete sentence about pointing device interaction
http://lists.w3.org/Archives/Public/w3c-wai-ua/2001JanMar/0421
[NOTE: I've implemented this one in the 19 March draft since I
don't expect that it will be controversial.]
Resolved: Accept this proposal.
d) Checkpoint 2.7: Solution for repair text should not be
minimal requirement.
Note: There is support for this proposal from Al and Denis.
http://lists.w3.org/Archives/Public/w3c-wai-ua/2001JanMar/0418
Resolved: Accept this proposal: This technique is sufficient
but not necessary to satisfy the checkpoint.
EH: Should that be in a Note?
CMN: I'm inclined to leave the sufficient technique is ok
for the checkpoint text, but indicate in the Note that other
solutions are possible.
(IJ: I think that that's what CMN said)
EH: I think that since it's not normative, then should be
outside the checkpoint.
IJ: But I want to make a stronger comment here: this technique
is ack'd by the WG to be sufficient. We could add to the Note
a better solution (e.g,. going to the Web to get a title of
a resource).
EH: I think we may need to provide more information about what
is expected.
IJ: We might avoid "may" and simply say "A UA satisfies this
requirement by providing. ..."
IJ: What is important, I think, is to get information that the
author provided. There may be useful information elsewhere in the
same resource or in other resources. We can just tell developers to
look around for useful information that the author may have provided
elsewhere.
Resolved:
- Mime type, URI reference, element are sufficient but not
necessary requirements.
- Adopt proposal (with possible editorial changes).
- In a Note, give developers a hint about what would constitute
useful information. Make clear in Note that other techniques
may be better (and give an example of a better technique).
e) Refer to conformance proposals regarding content/ui labels, input
device conformance, and conformance example.
http://lists.w3.org/Archives/Public/w3c-wai-ua/2001JanMar/0483
See also the proposal to address conformance through pointing
device and voice input and the question at the end of the
proposal about the shape of Guideline 1.
http://lists.w3.org/Archives/Public/w3c-wai-ua/2001JanMar/0452
I think this proposal subsumes Al's comments:
http://lists.w3.org/Archives/Public/w3c-wai-ua/2001JanMar/0440
IJ: Has anyone read the proposals besides EH?
DP: I read them.
MQ: I started to read but got confused.
/* IJ reviews proposal */
IJ: Part three is an example of how to use the conformance model.
IJ: My example suggested to me that it's necessary to identify
formats in a claim.
JG: You could have a general conformance claim requirement to
indicate the formats that are supported as part of conformance.
Resolved:
- For Content type labels: you must either say "I don't do type X"
or "For conformance related to content type type X, I support these
formats...".
/* Ian explains part II of the proposal:
input modality conformanced */
EH: I think these changes are editorial and good. They don't change
any requirements.
Resolved:
- Adopt input modality proposals in:
http://lists.w3.org/Archives/Public/w3c-wai-ua/2001JanMar/0452
and:
http://lists.w3.org/Archives/Public/w3c-wai-ua/2001JanMar/0483
/* Ian explains Part I of the proposal *
Resolved:
- Adopt proposal to label each checkpoint for content, user agent,
or both.
- As to checkpoint grouping labels, Ian may leave those
(informative) because they allow related checkpoints with
different priorities to be next to each other.
/* What should Guideline 1 read? */
IJ: What about "Support full user agent operation through the
keyboard"
JG: That works with the substitution model.
IJ: But what about 1.2? Awkward to have Guideline 1 only have
one checkpoint.
IJ: What about "Support full operation through keyboard input
and text output"?
JG: I like the terminology of G1, even if we don't have checkpoints
for device-independence. We are trying to highlight the concept of
device independence; I hate to lose that concept. You are supporting
device-independence when you do the substitution of input devices.
IJ: Maybe we can have a generic guideline and provide more rationale
why it's about dev-independence at the checkpoint level.
Resolved:
- It's ok to have an over-reaching Guideline 1.
Action IJ: Make the prose of the guideline and checkpoints explain
how the checkpoints relate to the goal of device-independence.
g) Executive summary (proposed by Eric)
http://lists.w3.org/Archives/Public/w3c-wai-ua/2001JanMar/0413
JG: We shouldn't hold up the document for this, and I have a few
comments.
IJ: I still intend to edit this. (And IJ has an action still on this).
JG: I think that the executive summary should talk about themes.
IJ: Doesn't the statement of the Guidelines cover this?
JG: But those Guidelines statement are in the TOC. I think the
summary should give a different view of the document.
/* We don't have to finish this on the call */
h) Search termation. Refer to ideas from David:
http://lists.w3.org/Archives/Public/w3c-wai-ua/2001JanMar/0474.html
DP: Is search wrapping notification any more/less important that
other notifications that may come from the search? A lot already
happens now (e.g., you're told before a search wrap). I think we
need to be alerted when there are no more instances found.
Resolved:
- Add requirement to 9.8 alert when no more instances are found.
-----------
NOT COVERED
-----------
- Issue 468: The "at least a majority" minimal requirement needs
review.
http://server.rehab.uiuc.edu/ua-issues/issues-linear-lc2.html#468
- Issue 467: Checkpoints 3.2/3.7: Toggle placeholders off
requirement:
http://server.rehab.uiuc.edu/ua-issues/issues-linear-lc2.html#467
- Al Gilman has suggested that we may have a way to deal with
SMIL captions for checkpoints 2.5 and 4.5.
-- We need to add to the Techniques document for
the following checkpoints 2.9, 5.6, 9.3, 9.5,
9.6, 9.7. Additional techniques are welcome as well.
