RDFa Core 1.1 has already removed @profile and changed @src, so the net effect would be to deprecate @xmlns.

Note that the spec already indicates some attributes (such as @xmlns) may not be present in all Host Languages (e.g. HTML5). There's also a note in B.4 Changes that @xmlns has been deprecated (although it's still used in examples). Taking this further and removing its use from examples would be a fairly small step that would take us all the way there.

Some amount of xmlns processing, even if not for prefix definition, will likely still be required for Exclusive Canonical representation of XMLLiteral values.
