Document the Active Select API in the handbook

Could the person in charge of http://drupal.org/node/50377 please update this page to document the Active Select API? I don't know who the author / maintainer of this handbook page is, which is why I'm posting this issue here. Here's the text that I'd like to see added to the page:

Sub-title: Active Select

Text:
The Active Select module (http://drupal.org/node/49976) provides a new type of form element called an 'activeselect'. When a user selects a new option (or set of options) from an activeselect box, one or more different select elements (the target elements) get their lists updated using AJAX. Module developers can use Active Select to create a 'drill-down' interface, where users can easily navigate and select from hierarchical information (e.g. selecting 'countries', 'states', and 'cities' in a form). For developer documentation, see the API.txt file included with the activeselect distribution.
