Thanks for sharing.

Some feedback.

- One of the problems with longdesc has been that its data type is not
obvious. The name should reflect the fact that it is a URL. e.g.
"aria-descriptionurl" or "aria-describeaturl" would be better.
"aria-descriptionurl" has the advantage of being a little harder to
confuse with "aria-describedby". It surprises me that after all the
problems with the naming of "longdesc" people are proposing adding a
similarly ambiguous name.

- What's the rationale for adding yet more attributes with the "aria-" prefix?

- Note that "epub:describedat" is not actually part of the EPUB standard yet.

- Please define what "content that describes the object" would be. For
example, Wikipedia used to use @longdesc to link to metadata about the
image but not to a text alternative. Presumably we don't want
@aria-describedat to be used in this way? Again, would it be
appropriate or not appropriate to use this attribute to link to a
transcript for media? Would it be good to distinguish between
descriptions and transcripts?
