Hello, I've been hitting my head against the wall for a few hours already, so I thought it would be a good time to ask before the house falls apart *wink*. I'm looking back and forth between the Zope and ZConfig sources and documentation to see if I can figure out how to have a Product (or a python package) to extend Zope's ZConfig schema (a.k.a. Zope/Startup/zopeschema.xml) without having to reach into the guts of ZConfig. It looks like the right way to do this would be to extend Zope's schema and then specify a different 'schemafile' to ZopeOptions, but that's not currently possible as Zope doesn't support the '-S schemafile' switch that ZDCtlOptions does. If what I'm looking for seems just stupid please tell me *wink*. All I want to do is to add a simple config 'key' to zope.conf without having to patch the Zope source. Having no other choices, I would go with having my own schema and configfile, but that would be sub-optimal. Thank you for any help, -- Sidnei da Silva Enfold Systems, LLC.
