I am sorry for my slow reply.  I have just recovered from my

I agree.   It appears impossible to mention namespace-based 
dispatching without opening a large can of evil warms.

Completely agreed.  We have tried to briefly mention the possibility
of using namespaces for dispatching, but I think we have open a can of
warms.  Let's avoid further delay.

Well, I think that this would open a different can of warms!

I would propose something like this:

  An XML document labelled as text/xml or application/xml may contain
  namespace declarations, stylesheet-linking PIs, and schema
  information among others.  For example, an XML document may have the 
  XHTML namespace and has a reference to a CSS stylesheet.  Such an
  XML document may be handled by application programs, each of which
  may relate to some of the namespaces, stylesheets, and schemata.  
  However, selection and invocation of such application programs is 
  outside the scope of this specification.

How do you feel?

I think that we should revise the latest I-D soon.
