I like it... You could go into more detail in the header php doc about
just what an element is.... a predefined form array with sane defaults
and processing + a theme function. I think thats what I gathered from
IRC talking with eaton.

I've added example_element.module [1] to demonstrate how to create a new
form item #type. I'd love some reviews.

Looks good to me, just need to build up the comments.  If it's of any
use to you, here is an attempt at a nice user-friendly description of
hook_elements.


"Form elements are already familiar to anyone who uses Forms API.
Examples of core form elements are 'textfield', 'checkbox' and
'fieldset'. Drupal utilizes hook_elements() to define these FAPI types,
and this occurs in the core function system_elements().


By implementing hook_elements in your own module, you can create custom
form elements with their own properties, validation and theming."

"Each form element has a #type value that determines how it's treated by
the Form API and how it's ultimately rendered into HTML. hook_elements()
allows modules to define new element types, and tell the Form API what
default values they should automatically be populated with."
