Personally, I think that it is OK if people come up with secondary  
uses for Web languages outside the Web but that Web language specs  
shouldn't address the perceived or actual non-Web uses at the expense  
of the Web (either by complicating the Web platform or by incurring  
the opportunity cost of the WG working on non-Web stuff).

Even now that the XML namespacing mechanism is in place, are SVG and  
XAML mixed in the same client DOM in practice?

Without intermixing, what's the problem?

There are plenty of custom XML vocabularies where the format is known  
from usage context anyway. For example, there's no need for Flickr API  
responses to assert being Flickr API responses. Also, the namespace on  
the Validator.nu XML output format is useless in practice. There's a  
namespace only because it is the XML convention these days. Specifying  
the vocabulary unambiguously doesn't help if XML document gets sent to  
a client that doesn't know about the vocabulary.
