Ah-hah!

This works from within my DTMLFile method, like so:

<dtml-let key1="val1" key2="val2">
   <dtml-var expr="my_dtmlfile_method(_.None, _, caller_namespace=_,
key1=val1)">
</dtml-let>

Then it is possible to use *both* key1 and key2 in "my_dtmlfile_method".
(In practice, key1 probably needed to be passed something other than
the value it already had to justify this call).
(Zope 2.5.1).

Thanks Dieter!

This is definitely going in my product's developer 
documentation. ;-D

Cheers,
Terry
