Well, OK, but this still means that “two xs:time values that have the same
canonical representation can be not equal”. This may well be intentional*,
but I think it should be at least noted in the definition of op-time-equal.
Note that the XQuery 1.0 spec does not mention XSD 1.1.

(*: In fact, I can find no use of the canonical form for xs:time in the
XQuery/XPath specs, including the F&O spec, so this is an external rather than
an internal inconsistency.)
