Actually I think our current spec already prohibits multiple imports (
or includes ) of components with duplicate names. So while you could do
two imports of the same namespace, it would only work if all the
components in the second had names different from those in the first.

		I think we need to specify that it is an error to import
or include two inequivalent definitions of the same component. A
processor should therefore not non-deterministically ignore imports
since that will lead to noninteroperability, i.e. one vendor may ignore
an incompatible definition while another raises it as an error. 
		In general, I think we need to tradeoff flexibility in
favour of interoperability, which means that we need to specify behavoir
more tightly.
