  Hum, that's a place where I would expect the XML Catalogs to take
a role in abstracting the file paths. I would still recommend to
use a canonical URL (is there one for relaxng.rnc one http://relaxng.org ?)
and have the catalogs remap to the actual file location. This was
really important as we deployed DocBook processing tools on the various
Linux distributions (and Solaris), I would like to be able to do the
same as I'm starting to push Relax-NG schemas (DocBook, XHTML1, SVG
are good candidate, as well as the RNG for RNG schema).
  It's less critical than when the reference ends up in the instance,
but would still helps a lot for system setup, tools setup and documentation.
