That's easy.  Strict conformance to the XML 1.0 specification, Third
Edition in particular.  The specification defines conformance criteria.

That is the *only* reason.  believe me.  I've been in all the wars.  And
even that reasoning has been widely debated.

I've never seen a single application of XBEL embedded in another
vocabulary.  Even if I had, I would advocate namespace-free for an XBEL-
only document, with an namespace only to be used in embedded cases.
