the "summary variables" of <dtml-in> are not provided for ZPT.
You'd have to roll your own, maybe using a Script.

For batching in general, see:
http://zope.org/Documentation/Books/ZopeBook/current/AdvZPT.stx
section "Batching Large Sets of Information"

For more details see the Batch class in the ZTUtils
module in the API reference.
