Yes, changing the time comparison functions to refer to XML Query
instead of XML Schema does not solve all the problems in my email.
It solves one of them (the need to specify time zones for all
times). But it doesn't solve the second problem (the problems
that arise when midnight GMT falls during normal business
hours, as it does in many parts of the world). Solving that
problem will require an additional change, such as adding the
time-in-range function.
Thanks again for your help,
