List of things that should be inside a forms package in my opinion.
Custom Design: Form layout should be simple to customize and not be based
around auto generating tables (if both are possible then of course the later
can be used).
Variable length lists: It should be possible to add form elements on the
client side and bind them on the server side. An example of this would be a
list of addresses. A programmer should be able to add a new address widget
client side without problems when binding server side.
Validation: Complex validation scenarios should be simple and should fit
into the normal validation pipeline. An example would be validating that if
a checkbox is selected then a textbox becomes required.
All validation errors should display around the same time, e.g. if a type
validator fires it should not prevent other validators from firing after it
unless those validators depend upon that type data.
These are just my thoughts based upon my experiences writing forms. I can't
really utilize any framework that doesn't implement these features for the
types of projects I do.
If you need any more details/clarification I'd be happy to help.
