Because they don't fit ZPTs requirements (well-formed XML/HTML),
mail messages are actually one of the things we use DTML for
"normatively" (others are generating CSS and JavaScript).  We
changed the mechanism by which the DTML is called, however;  rather
than making it the top-level page, we call it via an intervening
page template or Python script.  For example, look at the "password
reminder" mechanism in CMFDefault:

   - The "I forgot my password" link takes you to a form, 'password_form',
     generated via ZPT;

   - The "target" page of that form is a PythonScript, 'mail_password';
     this script just calls the 'mail_password' method of the registration
     tool;

   - The tool's method looks up the information for the user, and
     then calls a DTMLMethod;  finally, it returns a ZPT confirmation
     page, 'mail_password_response'.

   - The DTMLMethod, 'mail_password_template', formats and sends the
     mail;  it has *no* UI impact at all.
