Um, I have to acknowledge what Dare said earlier in defense of
xs:import -- applications _must_ be allowed to protect themselves
against bogus or simply inappropriate/stale/premature schemas.

The fundamental principle behind the approach taken in W3C XML Schema
to schema location strategies is that you cannot provide for all
legitimate needs by giving _either_ users _or_ applications absolute
