No, Henry. A substtantial proportion of application use no schemas
whatsoever past design time. Yes, IF you have a schema language
that supports QNames as a type and IF you have a such a schema for
the XML language you're using and IF you're willing to take
the overhead of schema validation at run-time, THEN there
is a way for an XML processor to tell whether QNames are
hiding in content. Otherwise not. -Tim
