Naive question: don't the 'xmlrpc' or 'soaplib' products from Pythonware have
this kind of code in them? Having asked that, if they do then I have probably
reinvented the wheel on previous occasions myself.

This works very nicely indeed! One perverse thing I did try was to put my own
persistent objects inside each other, but it would seem that it would be
impossible to recreate the object hierarchy just from the XML files, although
the storage of such hierarchies was handled gracefully by the persistence
mechanism (recording the persistent class of the offending attributes in the
XML).
