I'll write a separate response, but: This cannot happen. If you
install a new Python release, it won't take over an existing PyXML
installation - you will have to explicitly install PyXML again for
that Python installation.

Installing PyXML won't downgrade you XML libraries: The _xmlplus
version check is designed to prevent that.

That would break a lot of existing code.
