- which XForms controls can be custom controls?
- All except upload? And not only controls can have bindings but all UI elements. (Have to make UI elements to use XTFB) -OP
- when is the different functions in nsIXFormsUIWidget called?
- what happens at page load and close?
- which attributes are set on the xforms control (appearance, type, etc.)?
- security issues? (upload could be a good candidate for spooky stuff...)
- Example of a custom control that changes how a data type is bound to a control. For example boolean to a yes/no radio button no a checkbox.
