        	<xs:documentation>Description of the extender pattern configuration.
The extender tracks extensions. The particularity of this architecture-style is that extensions are packaged in different bundles. An extension is detected by analyzing the bundle. The mark is currently a header in the bundle manifest. At each time a matching bundle appears or disappears, a callback is invoked. </xs:documentation>
