[Zope] XML Document

Hello, I would like to package FreePM (http://www.freepm.org) for Debian. This package depends from XMLDocument which I found at http://www.zope.org/Members/jerome/ZCPL/Products/XMLDocument/XMLDocument-1.0... . Unfortunately this file doesn't contain the slightes hint about the author of this package nor a license. This permits distributing it in Debian. Could someone enlighten me about authorship so I can ask for a valid license? Kind regards Andreas.
