Aaahh, yes.

I should have thought of this earlier... I use this recently learned
trick on an internal system at the office:

<!--#in sqlSelectJobOffer-->

  <!--#var expr="_.getattr(PositionDescriptions, pd_doc_name)(_.None,
_)"-->

<!--#/in sqlSelectJobOffer-->

where PositionDescriptions is a folder in my acquisition hierarchy and
pd_doc_name is a column returned in the SQLMethod sqlSelectJobOffer
which contains the id of the document I want to insert.  Of course, you
could hijack the pd_doc_name earlier in the DTML Method and/or stuff it
into the REQUEST.
