True. With BaseX 10, XQuery compilation was split up into a static
(logical) and a dynamic (physical) step to allow for a more fine granular
locking. In the static compilation, your expression will be rewritten as
follows:
collection('i_do_not_exist')/users/user[@name=()]
→collection('i_do_not_exist')/users/user[false()]
→collection('i_do_not_exist')/users/()
→collection('i_do_not_exist')/()
→()
