Part of this question is if the test suite should continue to change after the specifications are released. I certainly see the advantage of having tests that verify that default prefixes, terms and vocabulary definitions are properly handled by a processor.

It certainly would. I believe the intention was not to update it too frequently, but I don't believe there's an announcement mechanism; there should be.

I agree that including a history of changes to the document, at least in a human readable form is something we should do.

About every 6 months is I believe the frequency we were looking for, but I'm not sure that's documented anywhere.
