Resources of the drawing framework are panes, views, tool bars, and command groups. One URL describes the type of the actual resource. A sequence of URLs (typically one, sometimes two) specifies its anchor, the resource it is bound to. The anchor typically is a pane (for views), or it is empty (for panes).

The resource URL may be empty. In this case the anchor is empty, too. Such an empty resource id does not describe a resource but rather the absence of one. Instead of an empty ResourceId object an empty reference can be used in many places.

The resource URL may have arguments that are passed to the factory method on its creation. Arguments are only available through the getFullResourceURL(). The getResourceURL() method strips them away.
