[Python-modules-team] Bug#468622: CHANGES file says zsi dropped the PyXML dependency

[Savvas Radevic]

I was trying to merge the new version for Ubuntu:
https://bugs.edge.launchpad.net/ubuntu/+source/zsi/+bug/237674

And I noticed that CHANGES says that upstream has dropped python-xml:

Change for 2.1.0_a1 released 31-Oct-2007:
    -	No PyXML Dependency, use minidom by default (much faster)

Is it necessary for the binary package python-zsi (debian/control) to
depend on python-xml?
