If a spec makes a normative reference to XML then it gets whatever
semantics are embedded in the XML specification. If the infoset was part
of XML as it may be one day then they would get those semantics. And if
there is an entity reference then they can't complain if a parser for
their app makes a network transaction to resolve the entity.

If they wanted to use only the syntax and override all or some of the
semantics (e.g. ignore entity references) then they could do that. But the
namespaces spec builds on the semantics of URIs -- it is the very
semantics of URIs that make them unique. Without those semantics I could
build an namespace URI without impunity.

"Silence," wrote Melville, "is the only Voice of God." The assertion,
like its subject, cuts both ways, negating and affirming, implying both
absence and presence, offering us a choice; it's a line that the Society

Friends could silently endorse while waiting to be moved by the spirit
to speak. - Listening for Silence by Mark Slouka, Apr. 1999, Harper's
