If that means either creating a new URI which starts with
http://www.w3.org/2001/XMLSchema _for any purpose_ including as a namespace
name, and not documenting this in XML Schema, or binding the prefix "xsd" to
other than http://www.w3.org/2001/XMLSchema , then no.

Again, would you object if I were to redefine the usage of rdf:about etc.
("rdf" bound to the RDF namespace) and widely distribute software, with a
small disclaimer at the bottom "this close to RDF"? Perhaps acceptable to
the RDFIG in a strawman situation, but don't unleash this upon masses of
unsuspecting web developers who will simply get confused.

Actually a RELAXNG grammer can.

When you issue a W3C recommendation, it becomes hardwired as a compatibility
issue for as long at the web as we know it exists. Do it correctly. Make it
something you will be proud to have your name on.
