This is the format of the comment form used by WCAG
[http://www.w3.org/WAI/WCAG20/comments/guidelines.php]. Let's use this as a
general structure for our musings on the list. When we have reached
consensus on an item, it will be easier to transfer to the actual form and
submit it.

Item Number: Success Criteria 1.3.1
1.3.3

4.1.2
 4.1.1 ("parsed unambiguously")
Appendix A: Glossary

Comment Type: Technical (or Wording)

Comment (Including rationale for any proposed change):
"Programmatically Determined" is a user agent function. the language in
checkpoints seems to point more at what a UA should do rather than what the
author should do or provide.

Proposed Change:
<old>
1.3.1 Information and relationships conveyed through presentation can be
programmatically determined and notification of changes to these is
available to user agents, including assistive technologies.
</old>

<new>
1.3.1 Information and relationships conveyed through presentation are
provided using technology specific accessibility techniques and notification
of changes to these is available to user agents, including assistive
technologies.
</new>

<old>
1.3.3 When the sequence of the content affects its meaning, that sequence
can be programmatically determined.
</old>

<new>
1.3.3 When the sequence of the content affects its meaning, that sequence is
provided using technology specific accessibility techniques.
</new>

This is the first 2 success criteria. The language may need reworking for
each SC. It is difficult to make a sweeping replacement, each SC must be
reworded. The definition also needs to be eliminated.

"Programmatically Determined" is a user agent function. the language in
checkpoints seems to point more at what a UA should do rather than what the
author should do or provide.

the following checkpoints were at issue
1.3.1
1.3.3
1.3.4
2.4.8
3.1.1
3.1.2
4.1.2
and 4.1.1 ("parsed unambiguously")

it seems that WCAG is really means by saying "programmatically determined"
in the above checkpoints...
is that authors should write/provide (content, data, text, whatever) using
technology specific accessibility techniques.

the author creates content using specific technologies (defined in a
baseline). These technologies each have (or should have) specific
accessibility techniques, features, and requirements. The content creator
can only follow the requirements and techniques of the baseline technology.
The author can only assume/hope that the UA will render the content
accessibly.

It is up to the UA to programmatically determine what to do with the
content; or to parse the author supplied content unambiguously.

will discuss more on the call.

	1. ACTION: CL to find problematic instances of "programmatically
determined" or other user agent assumptions [recorded in
http://www.w3.org/2006/05/11-ua-minutes.html#action01]
	2. ACTION: JA to Help CL to do formulate re-phrasing. [recorded in
http://www.w3.org/2006/05/11-ua-minutes.html#action02]
