Definitely use page templates rather than DTML. The biggest problem doing 
WAP with DTML is that unless you are very VERY careful you will end up 
sometimes producing pages that aren't valid XML. You then waste ages trying 
to figure out why the gateway returned a totally useless error message.

With page templates you shouldn't be able to produce bad XML (unless you 
try), and you can use on-error on an outer tag to return a meaningful error 
page.

I have updated the WAP howto on the Zope site to suggest that page 
templates may be a better solution.
