Are you only considering formats that are directly supported by current
user agents and office applications, or also formats that can be converted
into more popular formats?
I think you should also have a look at DocBook, which is being maintained
by OASIS. I believe the DocBook Technical Committee have looked into
DocBook accessibility (DocBook actually defines structure and semantics, not
presentation) and the OpenOffice.org project has also worked on DocBook
support. Below are a few links:
- <http://en.wikipedia.org/wiki/Docbook>;,
- <http://www.oasis-open.org/docbook/>; (DocBook Technical Committee),
- <http://xml.openoffice.org/xmerge/docbook/UserGuide.html>;,
- <http://xml.openoffice.org/xmerge/docbook/>; (DocBook Filters in OOo).

Best regards,
