Yes, we have a little pile of test data:

I don't mean for anybody to refer to the .../rfc2445-formal schema
from their data!

The new schema has more constraints in it, but there are only a few
small changes to the way the actual data works (enumerated values
are strings and Valarm is a component and maybe a couple others).

i.e. the new schema is intended to describe almost the same vocabulary.
I updated the conversion tools and test data, and I plan to update
the 2002/12/cal schema itself presently, unless somebody objects.

Yes, event sherpa and cwm and various others. Anything in particular
you want to do?

Annotate the HTML? How? Have you considered GRDDL?
