Bug 198971 [CommonNavigator] Provide extension schema for setting help ID
I haven't been able to find a way to set the help ID for a view using the common resource navigator. It seems that having schema support for this would be the best way to handle this.

INavigatorViewerDescriptor {
	
	/**
	 * {@value} (boolean): True indicates the ITreeContentProvider.hasChildren() 
	 * should force plugins to load if necessary <b>false</b>).
	 */
	public static final String PROP_ENFORCE_HAS_CHILDREN = "org.eclipse.ui.navigator.enforceHasChildren"; 
	static final String TAG_INCLUDES = "includes"; 
	static final String TAG_EXCLUDES = "excludes"; 
	static final String ATT_IS_ROOT = "isRoot";
