Um, I _think_, as I read the current CURIE spec. [1], this is profoundly misleading. The immediate semantics of a QName, in content or as an element or attribute name, is an expanded name, that is, a pair of a namespace name/URI and a local name. The semantics of a CURIE is a URI. For a QName, you form the pair by splitting it on the colon, looking up the prefix in the in-scope namespaces to find the namespace name, and you have the pair. For a CURIE, you split at the colon, look up the prefix, and prepend the result to the bit after the colon. So, in Norm's example <myvocab pointer="x:foo" xmlns:x="http://example.org/"> <h:div someAttribute="x:foo"/> </myvocab> if someAttribute is interpreted as a QName, its value is < "http://example.org/" , "foo" > whereas if it's interpreted as a CURIE, its value is "http://example.org/foo" which is seriously different. Different semantics, please use a different syntax! ht [1] http://www.w3.org/2001/sw/BestPractices/HTML/2005-10-27-CURIE - -- Henry S.
