Modification is OK (at first, see below) for the first indexes, but an
error is raised while starting Zope for the DateTime indexes, because
"class" attribute points to a method name :

        zope.configuration.config.ConfigurationExecutionError:
        exceptions.TypeError: type_ must be a type, class or module, not
        a <function DateTimeValueIndex at 0xb672510c> in:
        File
        "/usr/local/zope/3.2/var/lib/python/zc/catalog/configure.zcml",
        line 58.3-66.3
             <content class=".catalogindex.DateTimeValueIndex">
               <require
                   permission="zope.ManageServices"
        
        interface="zope.app.catalog.interfaces.IAttributeIndex
                              zope.index.interfaces.IStatistics
                             "
        
        set_schema="zope.app.catalog.interfaces.IAttributeIndex"
                   />
             </content>

After removing this modification for the two last indexes, I can access
catalog's "advanced" management screen without error, but information is
not really fine : on a SetIndex for example, "Document Count" and "Word
Count" columns are displayed as "<security proxied BTrees.Length.Length
instance at 0xb4dc052c>" instead of their numeric values...
