[Zope] Passing parameters using DTML

[John Poltorak]

Can someone provide an example of passing parameters using DTML?

I'm sure this must be doable, but don't see an example in the Zope Book.

I assume it would go something like

<dtml-var var1 parm1 parm2>

but how would var1 pick up parm1 parm2?
