Granted, but the use of the Namespaces Rec facilities allows names to be
assigned in a single document by separate authorities, as long as nobody
assigns a namespace name for which they have no authority.

This is more of an arbitrary WXS rule than anything else.  In RELAX NG,
the namespace of a name and the schema document in which it is defined
or used is completely orthogonal.  You can have single schema documents
that make use of names from many namespaces, and you can compose schemas
out of parts which contain names from one or more namespaces.

But this is XML-Dev, where out-of-scope discussions are in scope.
