alt curly braces proposal in the editor's HTML5 draft

Hi Ian,

Has the  curly braces proposal from the img section of the editor's
HTML5 draft [1] been either discussed with or approved by the
Protocols and Formats Working Group (PFWG) with regard to conformance
with:

- Web Content Accessibility Guidelines (WCAG)
- Authoring Tool Accessibility Guidelines (ATAG)
- User Agent Accessibility Guidelines (UAAG)

It seems as if this proposal is for meta data and might fit better in
a separate img attribute. In any event, it doesn't appear to be a text
equivalent per WCAG.

The HTML WG needs to be sure deliverables satisfy accessibility
requirements [2]. PF are the go to guys for guidance in accessibility
matters. Did you ask them?

Thanks.

Best Regards,
Laura
