I think I'm persuaded. It seems that (apart from a syntactic interaction with
edge cases involving lone-slash), the only impact is on expressions that use
"/" to the right of "!". And it's hard to construct realistic examples where
(under the current rules) such a use of "!" is usefully different from "/",
given that the lhs of "/" has to be nodes, and the "/" does any
document-ordering that the "!" might otherwise have prevented. So the current
precedence rules don't allow you to do anything very useful, wheras the
proposed precedence rules allow expressions such as
$page//@href ! doc(.)//title
where the fact that "!" doesn't do document-ordering is potentially useful.
