RelaxNG schema for introspection files

[Ross Burton]

Hi,

I recently hacked up a RelaxNG schema for the introspection format
(attached), useful because emacs+nxml-mode can validate in realtime from
a relaxng schema.

It works for me with all *pure* introspection files, but because the
schema is strict it doesn't like extra namespaces in the document. This
means whilst it works for a "normal" introspection document it will say
that a document with inline documentation or Telepathy elements will
fail to validate.  Anyone who knows relaxNG better than I do is welcome
to tell me how to fix this. :)
