That's interesting, and also reiterates comments about the 
coexistence of ztp and dtml.

We're also using dtml for non template kinds of output like CSS and 
JavaScript, but had yet to put email in that category. Makes 
perfect sense though. It would seem a rule of sorts could be 
applied when doing development -

o well formed, structured (HTML,XML, and XML derivatives) = Page 
o not well formed or structured (mail, CSS, JavasScript, structured 
text, etc) = DTML

Sounds like another piece to the DTML to ZPT conversion
