Welcome in the club:-)

Correct.

I'd suggest we remove HTML5 (and HTML4, I suppose) from anything using xml:lang or xmlns (with the exception of the stated use of xml:lang as a namespace-less attribute, which I'd rather see go away from HTML5+RDFa).

See my previous mail. This may remove way too much, we should be careful about this. For the time being I think removing the XML Literal version from HTML{4,5} makes sense.
