Update of /cvs-repository/Packages/ZConfig
In directory cvs.zope.org:/tmp/cvs-serv21256
Modified Files:
Tag: zconfig-schema-devel-branch
info.py matcher.py schema.py
Log Message:
Changes to the schema language:
- The minOccurs and maxOccurs attributes are gone
- To specify minOccurs==1, use required="yes" in the schema
- To specify maxOccurs=="unbounded", use a <multikey> or <multisection>
instead of <key> or <section>
This needs some code review and refactoring, but works.
