Bug #6244

Test case higher-order-functions-034
100%
Description
This test case is failing because it considers that
element(e)? is a subtype of element(e, xs:anyType)*
To quote https://www.w3.org/Bugs/Public/show_bug.cgi?id=21595, this is not the case, because element(e) allows a nilled element, while element(e, xs:anyType) does not.

I think that what is happening is that somewhere along the line, we're assuming that because the stylesheet isn't schema-aware, no element is ever going to have the nilled property, and therefore there's no difference between element(E, T) and element(E, T?). However, although there's no difference in what the two types match, there is a difference when it comes to the subtyping relationship.

The culprit seems to be XPathParser#3683 which ignores the ", xs:anyType" - code which I added on 2023-07-17 in the course of adding support for name test unions in 4.0.
Fixed for 12.x.
However, the code for 11.x is rather different, but the problem still occurs... Wrong: the test passes in 11.x
