I would use:

   <dtml-in "REQUEST.items()">
     <dtml-unless sequence-item> <!-- the value-->
       something wrong with <dtml-var sequence-key> <!-- the field name-->
     </dtml-unless>
   </dtml-in>.


However, as a user, I would not be too happy to get the internal field names.

Recently, I did something similar to you.
However, I used a list of dictionaries to describe the form.
Each list entry describes one form field as a dictionary
with keys "name", "title", "type", "condition", ...
The description is used both for creating the form and
for verifying that all requirements are met.
