no, presumably.

But schema describe document grammars (amongst other things) so giving
individual schema for each namespace used on attributes in the
document isn't normally what you want, normally you want the document
to be linked to a schema that gives overall constraints about which
attributes are allowed where, whichever namespace they come from.
This schema may well use schema that describe the individual
attributes but it doesn't just need to include these it needs to add
the constraints about where the attributes may be used. (which may be
no constraints at all, of course)
