Hi,
I should add that:
1. WAI-ARIA is completely valid in html5, it is not valid in xhtml, but it will
work exactly the same.
2. As for longdesc, which is not valid in html5, it will almost certainly still
be supported in the browsers / screen-readers that support it now. That is to
say that I can't imagine Firefox removing support for this attribute, or
disabling support on html5 pages.
Thanks,
Everett Zufelt
