[Zope] Does it exist a Zope product for creating/editing RSS files v1.0 (and/or 0.9)?

[Bocquillon Philippe]

Hello,

The SiteSummary Zope product permits to create RSS v0.91 files.
The RDFSummary product permits to grab RSS v0.9 and v1.0 files from other
sites.
 
Does it exist another Zope product permitting to create/edit RSS v1.0 and
v0.9 files?
If no, do you know if a Python based tool can do that?
