the same results when evaluated against a particular source document.

Do you mean that the two paths must be statically equivalent, in the sense
that (a|b) and (b|a) always produce the same result? Or do you mean that
they are equivalent in the context of a particular schema (for example a/*
and a/c are equivalent if the only permitted child element of a is c). Or
do
you mean equivalent in the sense that they produce the same results when
evaluated against a particular source document, for example (key('k', 'z'))
and (../b) might produce the same result?
