Scenario Examples

I have gone through Rick's scenarios document and create example queries for
many of the scenarios. The purpose of this excercise was to see what kinds
of problems the query grammar as it exists today has problems with. The
examples are below. You will see that one issue regarding XML has been
raised. I will send out follow-up mail with some proposed design solutions.

Thanks,
