Forms TODO
==========

BETA4 MUST HAVES
----------------

* CAPTCHA view helper
  * Accept an element, pull the "captcha" attribute, and call render() on the
    captcha
  * Potentially a "captcha" element, with a dedicated property?
* Remove "InputFilterAwareInterface" from forms

RFC Items
---------

* Builder component
  * Introspect a class for annotations and build a form
    * Each "element" can specify:
      * filters and validators to use to build an input for the input filter
      * attributes for use with the form element
  * Should be able to generate a form class
