I only have few minutes to write this post, but it should get you 
started. The trick here is the root plugin of the template for the 
article document type:

Search for the following code snippit in the url down below.

         <sv:node sv:name="root">
           <sv:property sv:name="jcr:primaryType" sv:type="Name">
           <sv:property sv:name="plugin.class" sv:type="String">
           <sv:property sv:name="wicket.id" sv:type="String">
           <sv:property sv:name="wicket.extensions" sv:type="String">
           <sv:property sv:name="extension.main" sv:type="String">
           <sv:property sv:name="extension.select" sv:type="String">
           <sv:property sv:name="extension.mixins" sv:type="String">


If you take a look at the following line:

<sv:property sv:name="plugin.class" sv:type="String">

You will notice that the plugin.class is different from all the other 
templates. Looking up the file on the class path, you might find out 
that it references to a wicket html fragment located at [2].


As you will see, the html file contains wicket id's like:


which resemble the CMS template configuration

<sv:property sv:name="wicket.extensions" sv:type="String">

I think you should be able to handle it from here on. If you need more 
help please let me know.

This might change in the next release, since in the 2.07.00 you should 
be able to do this from the template editor as well (choosing a layout), 
but i'm not sure if the actual configuration is different, since I have 
been away for about a month.
