[Mediawiki-l] Passing variables to extensions

[Carlos Jorge Andrade]

Hi,

Is it possible to pass variables (http://meta.wikimedia.org/wiki/ 
Help:Variable) to extensions ?

For exemple...

<myExtension snippet="Map" domain="domain.com"  
title="{{SUBPAGENAME}}" />

How do I set the page title as a parameter ? Is there any other way  
of doing this ?
