I think I mean this one, but I don't understand why you think the
modification is superfluous?

Definitely not this one. I tried to be very careful to not propose
something that would remove anything from the XHTML+RDFa spec. To be
clear, the XHTML+RDFa spec would assume about="" on the root element
(HTML), on the HEAD element and on the BODY element. The language used
to accomplish that is left as an exercise for Shane.

No, under the rules proposed above, and in XHTML+RDFa it would generate:

<base> q:r <http://manu.com> .
<base> a:b "aaaa".

No backward incompatibility.

Yes, that is what I meant to propose, sorry if that wasn't clear.
