Ah, thanks for clarifying. Yes, RDFa is definitely not alone in this 
regard. XSLT and W3C XML Schemas both use QNames in content (or 
attribute values). And new specifications often use them; my most recent 
encounter with them was in implementing Inline XBRL, which uses them 
pervasively.

To quote the TAG:
"Whatever the architectural ramifications of using QNames as identifiers 
in contexts other than XML element and attribute names, it is already 
established practice. It is simply not practical to suggest that this 
usage should be forbidden on architectural grounds."[1]
