I don’t see how they wouldn’t need knowledge of the doctype anyway in 
order to sensibly process the XHTML anyway. This is the case for rel + 
relNS as well, XSLT can do nothing with the attribute if it doesn’t know 
that NS contains a namespace, etc.

XSLT 2.0 has functionality to resolve QNames, see section 11 of the 
current Functions and Operators specification [1]. I have used this 
functionality already for an odd case, and although it’s not really 
compact, it works just fine.

With regard to rel and relNS, if you want to explicitly have to specify 
the entire namespace URI, instead of introducing something new wouldn’t 
it be better to follow RDF then, and have 
rel="http://example.org/namespace#something ?
