When people ask for generated XPath expressions, they are usually asking for
some kind of canonical path from the root to a node - typically a path whose
steps all use the child or attribute axis and whose NodeTests all consist of
an element or attribute name.

Even with this restriction, however, if the schema is recursive then the
number of possible canonical XPaths that can retrieve a node is infinite.
