+/** A resource id uses a set of URLs to unambiguously specify a resource of

+    <p>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).</p>
+    <p>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 XResourceId object
+    an empty reference can be used in many places.</p>
+    <p>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.</p>
