As proposed in <http://collector.zope.org/CMF/191> we would need to
support old and new indexes because Zope 2.5 doesn't have DateIndex /
What about adding additional methods to the CatalogableDublinCore
interface that return the values needed by the new indexes? This way
they could co-exist with the old indexes that use the old methods.
