I've just started playing with The Django Form Validation Framework on Google App Engine (from google.appengine.ext.db import djangoforms) and I got stuck googling how to customize forms using it. I was wondering whether the following are possible using the package:

• Add help texts beside/below input/select fields and textareas (e.g. "This field is required", "Example: qwerty123")
• Add/modify attributes for the input/select fields and textareas (e.g. adding the following attributes: class, id, name, maxlength, minlength, etc.)
• Add custom validations like checking whether a particular field should be unique or checking a value against a regular expression
• Modify the error messages
• Add another column to the table generated by the form

Also note that djangoforms.ModelForm is different from django.forms.Form.
