Hi! Is there any good documentation about how to implement your own elements through hook_elements()? I must confess that the example file provided on api.drupal.org doesn't seem entirely clear to me -- why do I want or not want '#input' to be true, when does '#process' get called (I tried to create my own element, but '#process' never got called), do I have to register the theme function via hook_theme (), what internal keys to the formapi should I be messing with, what are the standards for themeable elements -- is there any place I can go to find out these kinds of things?
