I'll take this opportunity to note that I expect to completely re-vamp
the "extension" support.  There's currently some machinery that tries
to extend components, and that hasn't been useful since schema
components are now loaded from Python packages.  I'm not aware of any
application of the current mechanism (though the basic component
support is used in just about every non-test schema I've written).

Before I rip that out, along with the associated tests:  Is anyone
*using* the component extension support?  If you're relying on a schema
loading an extension.xml file having a top-level element <extension>,
then you're using it, otherwise you aren't.
