There is a difference between what I may have in mind and what
recommendation the WAI-CG consensus document contains. I do not quite
understand why but whenever the WAI document is referred to it is referred
to as "my document", it is not, it is a set of recommendations [1] from the
WAI co-ordination group [2]. and one way or another this and other feedback
from the WAI-CG will have to be processed and responded to by the HTML
working group as it lies in the path of last call.


In the WAI-CG consenus document there are 2 recommendations that I am
addressing in this email:
"We recommend

   - that HTML5 state that "For guidance on accessibility requirements for
   text alternatives authors should consult WCAG
2.0<http://www.w3.org/TR/WCAG20/>
   ."
   - and that HTML should not provide any guidance that conflicts with WCAG.
   "

The first request is unambiguous to me, can you tell me what needs to be
made clearer? The second request is ambiguous as the areas where the WAI-CG
considers that the content of the spec conflicts with WCAG has not been
detailed. The WAI groups are in the process of a full review of the HTML 5
specification and I understand that details of conflicts, if any, are
forthcoming.

My personal preference is that a reference in the section of the spec
relates to text alternatives be added using text similar in intent to that
quoted above. the link should point to a section in the HTML 5 that lists
and links to the W3C specifications relevant to authoring accessible
content, providing accessible authoring tools and accessible user agents.
This section would include brief explanations of how these
specifications are relevant to the HTML5 specification.

I would obviously be pleased if the accessibility references that point
authors and software develoeprs to the relevant specifications were
prominent within the spec.
