[Zope] ZSQL Question - required type

I have created a ZSQLMethod which does an insert into a table. All arguments have the "required" type. When I test the method this works fine. The problem comes when I call the method through a DTML document as the required type seems to be ignored. Is this correct behavior? Is it normal to POST form data to an intermediate DTML document or direct to the query template? I need to do some data validation along the way.
