[Zope] Syntax for getting property sheet

If I have a ZClass with a property sheet called 'Info', how can I get access to the sheet when I DON'T have an instance of that ZClass to work with. Specifically, I want an ADD form for my ZClass that has an ID field and a dynamically generated section containing all the properties from 'Info' all on ONE from. I can't seem to figure out how to dynamically generate the property section without an instance to work with. -Jon
