[Zope] programatically deleting ZClass instances?

Could someone send me a code snippet showing how to delete a ZClass instance? I've been trying to use manage_delObjects([ids, REQUEST]) - Delete a subordinate object. The objects specified in ids get deleted. without success. (If it matters, the ZClass instances I want to delete are children of a container ZClass.) I'd even settle for a DTML solution although I would like to see how to use the above method ... Cheers, Darran.
