Just letting people know (in case they don't already) that any of the
documentation on drupaldocs.org (including the Forms API reference) can be
updated by anyone with CVS access. The stuff is in contrib, in the
documentation/developer folder (and in this case
documentation/developer/topics/forms_api_reference.html)

If it's something simple like adding a clarifying note (as specified above),
fixing a typo, etc. please feel free to "Just commit it (tm)" -- if it's more
involved, such as an entire re-write of a section or something, then please post
an issue under the documentation project
(http://drupal.org/project/issues/documentation) so it can get community review.

Thanks!
