One doesn't really need any new syntax.  If we consider complexTypes as
introducing a new namespace (which we're perfectly free to do - the NS rec
doesn't say anything about how you create or name a namespace, nor much
about what a namespace is) then xsi:type is an attribute that says "the
default namespace within this element is the namespace created by the
complexType with this name".  That's it.
