Side point on RSS feeds, 

We need to be attaching an RDF accessibility conformance statement (such
as EARL) to RSS data, so that a site will have a guarantee of the
accessibility level for the data content. Otherwise the accessibility of
the site using the feed is compromised.

Are people doing that yet?

Of course the end site can always lower the accessibility level of the
content, but that would be their problem.
