[Zope] Creating your own list to use with dtml-in

Hi, Can somebody tell me how I can create a list which returns a same list as with an zsqlmethod? for instance the following list {5:{name:'tom', address:'xxx'}, 7:{name:'Lies', address:'xxx'}} Now, I would like to use it as <dtml-in list> <dtml-var address> </dtml-in> Can somebody tell me how to do this? Thanks, Tom
