Why do you think people aren't trying hard to conform? Do you really
believe people are actually intentionally creating half-assed software
instead of the more likely scenario that the spec is too complex,
contradictory and ambiguous to implement correctly?
At least with W3C XML Schema, there is rationale for wanting to be
interoperable. I personally fail to see any reason why XQuery
implementers should go out of their way to try to be interoperable if
doing so would require undue difficulty on their end.
