[Zope] ZCatalog counting?

[Andy McKay]

But that assumes that they are all in the same folder... a ZCatalog query
where meta-type = 'DTML Document' followed by a simple sequence-length would
get around that. And I think (but dont quote me on this) that a ZCatalog
search is quicker than objectValues.
