Not for non-validating XML processors. Note that the common
implementation of XHTML is via non-validating XML processors, IIRC early
versions of Mozilla and Opera with XHTML support did not even support
entity references like &ouml; for this very reason. One could read the
conformance section in a way that the xmlns attribute must be specified
in the document. I remember that several people asked the HTML WG for
clarification on this but I do not remember any answer.
