Phillip Eby and I both checked new functionality into ZConfig today; the documentation has been updated. If these changes are still looking good in a week or two, I'll plan on releasing it as "ZConfig 2.0". Both sets of changes revolve around schema extension, but they support different things. Phillip's changes allow one schema to be derived from one or more other schema. My changes allow configuration files to load additional schema components. Please try these changes and see how they work for you. -Fred -- Fred L. Drake, Jr. <fred at zope.com> PythonLabs at Zope Corporation
