Don't try to make namespaces do too much. Namespaces are for universal
names. Anything else, whether it be validating mixed vocabulary documents or
versioning schemata, is going to have to rely on a mechanism other than
namespaces (although namespaces might be part of the solution).

XSL is an excellent example of namespaces in action. XSL has its own
template vocabulary and this vocabulary gets mixed with whatever vocabulary
is used for the result tree. To avoid possible name clashes between names in
the template vocabulary and those in whatever vocabulary is used for the
result tree, you can use names spaces.
