What's your view to interoperability if query expression
uses datatype such as xsd:dateTime and operator
for the query is not equality nor not-equality?

How would an otherwise DAWG compliant server - which
didn't support xsd:dateTime (assuming dateTime wasn't part of
DAWG rec, which I hope it will be) - evaluate the expression?

An error message quite simply?
