that means that NumberString|$associations/NumberString selected more
than one node, in xslt1 the other nodes would have been silently
discarded, but in xslt2 its an error.


would avoid that, but return a sequence of numbers and again (in xslt2)
this is an error.

If you just want to sort on the first NumberString descendent of each
item you can use [1] to ensure the path just selects one item.
There is something strange about your sort key though


starts with a variable, so in particular it does not depend on the item
being sorted, so the sort key (from this branch of the union) is a
constant value (within this scope). Sorting a list with a constant sort
key is a non-op?
