I mentioned this elsewhere, but from my conversations with W3C Schema people, the optionality of "schemaLocation" is meant to be for exceptional cases, and definitely not the rule, so I don't think that best practice methods need (or should) assume that it cannot be relied upon.  After all, deciding on what not to leave out is part of what best practices are about.

     Cheers,
          Tony.
