Hi, I'm a newbie in Jboss Portal.

I'm just reading on how to create layout and theme, and I'm a bit confused.

I noticed in the default 'generic' theme (/layouts/generic/index.jsp). There is a call to the 'AjaxScripts' region.

<p:region regionName='AJAXScripts' regionID='AJAXScripts'/>

But in the layout descriptors (portal-layouts.xml):

 <layout>
 <name>generic</name>
 <uri>/layouts/generic/index.jsp</uri>
 <uri state="maximized">/layouts/generic/maximized.jsp</uri>
 <regions>
 <region name="left"/>
 <region name="center"/>
 <region name="navigation"/>
 </regions>
 </layout>

So, when rendering 'AjaxScripts', what exactly it is referring to?
