That syntax is not in the latest XQuery draft.  It should be:

module namespace auth = "myAuthenticate";

You should change "define" to declare" - even though Qexo for now
accepts either.

"import" must be in the query prolog - i.e. at top level.

Possibly, but I haven't tested it.  Modules in general are
"in progress" - both in my implementation and in the standard.
(There is some sentiment for delaying them until XQuery 2.0,
as the current specification has some major problems.)

Probably because you'r using the wrong syntax for the module
declaration.
