So it turns out this is based on something called the IETF XML
Registry (RFC 3688) [1], which seems to me to interact with various
aspects of Web architecture.  It provides for 'registering' assigned
URNs for namespaces, DTDs, W3C XML/RDF Schemas and public identifiers.

It mandates the creation of a server by IANA (not yet in existence, I
don't think), which will serve the definitive definition of the
registered things.  It also says that you shouldn't count on the
server to give you DTDs or schema documents . . .

It says nothing whatsoever about versioning. . .

This whole thing makes me quite nervous . . .
