XML complexity, namespaces (was WG)

We're writing hypothetically, about a mechanism (namespaces == architecture)
which is poorly defined, but ...

I would take "used to do architectural forms" to mean that the information to
be inferred from a namespace declaration would supplant (some portion of) that
which would otherwise have been provided by existing architectural
declarations. Otherwise namespaces are just "architecture-neutral".

When I wondered about how this might work, it occurred that the identity
between the URI in a namespace declaration and that in the system-id of a
IS10744:arch PI might be used to infer mappings equivalent to those provided
by the individual architectural mapping attributes.

The problem with this is that it provides no means to map the local parts of
universal names. Without such a means, either a given element type maps to
exactly one architectural form (my original question), or the local parts of
the respective type names must be identical in all architectures (which would
seem an equally severe restriction).  That is, the standard architectural
declarations are still necessary and, again namespaces are "architecture neutral".

What mechanism were you supposing?
