Hello,
See message below. The UAWG appreciates the adoption of the proposed wording
changes to the ACCESS Module for XHTML2.  We have received your concerns.
UAWG is having a conference call today and will address the 2 issues (Should
vs Must, and definition of 'session') at the top of the agenda. UAWG will
hopefully have responses to these issues today. 

Minutes from the telecons focused on Access Module Discussion on May 8
http://www.w3.org/2008/05/08-ua-minutes.html 
And May 13 http://www.w3.org/2008/05/13-ua-minutes.html 

Jim Allan, Co-Chair UAWG

Gregory,
This needs a bit of discussion with the group. We have a call tomorrow and I
will add it to the agenda. UAAG10 was release in 2002 and used Priority
Level to determine importance. Additionally, the wording of the normative
checkpoints is not precise in their intent. The referenced checkpoints (9.5,
9.6, and 11.3) are all Priority Level 2. As such the group agreed on an RFC
2119 SHOULD to align with our interpretation/mapping of Priority Levels to
RFC 2119. 
That said, given the strong feelings of the XHTML2 working group further
review is necessary.

Additionally, defining 'session' will also be addressed during the call.

Jim
