By 'whatever' I meant that it might return a document
or invoke another object method that returns a document 
or invokes another object method or ... whatever.

Okay, just getting independent confirmation that I'm 
not totally off-base helps.  Or at least I'm in good 
company.

At any rate, the round-trip nature of dtml to object
methods to dtml to whatever probably makes useful
how-to fodder.  How will the proposed JimF changes
to DocumentTemplate affect this idiom?
