Indeed the W3C XML Schema specification says this explicitly [1]:

 The author of a document uses namespace declarations to indicate the
 intended interpretation of names appearing therein; it is possible
 but not guaranteed that a schema is retrievable via the namespace
 name.

XSV supports RDDL at the namespace URI for this purpose, and gives
user control on whether namespace URIs are dereferenced or not.
