When trying to use predicate patterns in XSLT 3.0 (https://www.w3.org/TR/xslt-30/#doc-xslt30-patterns-Pattern30) I was kind of astonished that

.[predicate1][predicate2]

and

.[predicate1 or predicate2]

are allowed while it is not allowed to form a union of two predicate patterns alike

.[predicate1] | .[predicate2]

Why is a union of predicate patterns not allowed?
