I think that makes perfect sense. Most people ARE comfortable with the
paradigm of server side checks/validation and if we are talking about XForms
over HTTP, server side validation becomes a must. It will ease bridging to
XHTML/HTTP a lot easier.

As I already replied to Brian, there are 2 situations where batch validation
(validating all the fields, probably, when submitting) is needed:

1 - Checking for mandatory fields. Because the user has freedom to jump
around the form, skipping fields, so that checking-as-you-type wont work.

2 - Applying validation rules (constraints) that work by relating more than
one field (ex.:  if field "A" is filled then field "B" is mandatory, or
field "C" must be greater than field "D",...)
[Mainly what youve said, John]

Also, back-end validations (business rules) can issue multiple "warnings",
so that my current XML+XSLT+Javascript solution, make those appear and
behave identically (browser-detected errors catch before sending, and
"business objects"-detected errors returned after processing the posting).

PS.: Arnas Opalnikovas and Elizabeth Hinson, asked me to show/detail my
current implementation, but Im bound to a NDA from my employeer... Sorry.

Hi Brian,

I would agree, except that I think the dynamic constraint language can
run calculations on the validation constraints, and if so, many
simultaneous things can break and the result of one user change, perhaps
even on pages other than the one the user is viewing.

I expect an XForms form would try to validate when any

field is edited or (at the latest) when any field
blurs.  Batching errors until form completion doesn't
seem as user-friendly.
