So, the nice trick would be to make sure your "uri" namespace prefix is
properly dereferenceable, so that once you've provided these
definitions, folks can just use uri:scheme, etc, as if they were
builtins.  I think that will work, or at least it should.  (You might
need to give cwm certain flags.  It's been some years since I used that
feature.)  If you think about what you're doing as providing a standard
library for parsing URIs, then it may not seem quite so messy.
