Obviously I'm not aware of all Zope users, or all ParsedXML users. I am
however pretty sure (from following the mailing lists and helping
in the development) that the installed base is likely to be orders of
magnitude smaller than, say, ZEO, and definitely a *lot* smaller than Zope.
I myself use XMLDocument, the predecessor to ParsedXML in a fairly large
production environment and thus am aware about upgrade issues.
XMLDocument is however not at all developed by ZC anymore, so obviously
I understand the upgrade problems.
For instance, it is likely less than 100, unless everybody is perfectly
happy with the thing and wouldn't subscribe to the zope-xml mailing list,
which has about a 100 subscribers not all of which use it.
So, as a counter argument I can come up with some contrived
analogy to Unix 'make'. :)
Anyway, I'll stop arguing now and wait for the zope-xml reactions to
an informal poll. The few reactions I got are diverse so far, so we'll
see. Actual data will help us more than this pointless discussion (yes
I *know* one should be careful generally in upgrades!).
