Alas, this is so. As W3C says, "An implementation is under no obligation
to generate the same identifiers each time a document is transformed."

Actually, the available implementations are usually "stateless" as regards
generated identifiers, but, any way, the document can "slightly" change
after some "previous" transformation (for instance, an absent XML
declaration can be added) and, as a result, the identifiers will also
change even in the case of a "stateless" implementation.
