I disagree with Timbl here; you cannot "follow your nose" from application/xml in RFC 3023 to document-specific processing (i.e. no namespace dispatching)
RFC 3023 says;
An XML document labeled as text/xml or application/xml might contain namespace declarations [...] Such a document might be handled by applications that would use this information to dispatch the document for appropriate processing.
"Might". Not "Will"
