--- Comment #1 from Michael Kay <[hidden email]> ---
The incompatibility observed in an XSLT 3.0 test case in bug #27140 should be
noted in Appendix J.1 of the XPath 3.0 specification.
Specifically, if U is a union type with T as one of its members, and if E is an
element with T as its type annotation, then in 2.0 the expression "E instance
of element(*, U) returns false, while in 3.0 the same expression returns true.
