Post a follow up: 
http://drupal.org/project/comments/add/29465

 Project:      Drupal
 Version:      cvs
 Component:    base system
 Category:     tasks
 Priority:     critical
 Assigned to:  adrian
 Reported by:  adrian
 Updated by:   chx
 Status:       patch (code needs work)

A few notes from my conversation with adrian. valid => array('integer',
'uid') for this to work you need function valid_integer($element) and
valid_uid($element). $extra for form_select is legacy and really
needed.

This is the first check in of the new forms api code.


The system has been designed to co-exist with the current forms api,
and is contained in a new
include file (includes/form.inc).


Forms are now defined in their component arrays, similar to how menu
items are defined.


example :

<?php
 $form['body'] = array(type => 'textarea', default_value =>
$node->body, cols => 60, rows => 60);
?>


Elements can also be nested, and the $edit follows this definition. For
instance :

<?php
 $form['author'] = array(type => 'fieldset', title => t('Authoring
information'), collapsible => TRUE, collapsed => TRUE, weight => -1);
 $form['author']['name'] = array(type => 'textfield', title =>
t('Authored by'), maxlength => 60,
                                 autocomplete_path
=> 'user/autocomplete', default_value => $node->name, weight => -1);
?>




All the properties used are defined as constants, and are documented
for each of the elements, and individually.

A patch for node.module, blog.module and taxonomy.module that changes
them to use the new form format. This patch is very far from complete,
but I wanted to get the code out so that i'm not working alone anymore.

The actual patch =) 


I forgot to mention, this adds a new hook .. namely hook_elements,
which allows us to define the defaults for the elements (ie : cols and
rows for textareas) meaning they don't have to be defined for each of
the elements.
