         This extension point facilitates the configuration of providers for the marker navigation service
         (&lt;tt&gt;org.eclipse.gmf.runtime.common.ui.services.marker.MarkerNavigationService&lt;/tt&gt;).
         &lt;p&gt;
         The marker navigation service enables Xtools clients to perform the navigation feedback when the
         user double clicks on or &quot;goes to&quot; a marker reference. The attribute values defined on the marker
         identify a location or locations in the resource that are of interest to the user. The feedback 
         associated with navigation to that location depends upon the resource and its associated editors. 
         The feedback might simply be selecting the appropriate object(s) specified by the marker&apos;s location
         or the feedback could involve a separate dialog to describe the reason for the marker (e.g., errors). 
         &lt;p&gt;
         In order to make use of the marker navigation service, an Xtools client should define its own marker 
         types and creates the marker instances on the appropriate resources. Markers created on the 
         workspace root are not navigable.
