I guess not.  :-)  It does raise the question of whether PUBLIC & SYSTEM will
always point to DTDs.  While XML Schemas now are referred to using PIs, it does
seem a bit silly to use one formalism for DTDs and another for Schemas, just
because of historical limitations in the DOCTYPE.  I would be nice to be able to
refer to a DTD, an XML Schema, a RELAX schema, and Schematron schemas (all of
which may refer to the one document).  I bet some users could find a good reason
to resolve to a database schema matching their XML format.  I expect some of
these entities to be less widely used than stylesheets, of course, but no less
important to particular groups.

Please do have keywords for the most commonly used items.  Please also have a
clear extension mechanism.

     Cheers,
          Tony.
