<!-- Inspector-specific RDF attributes
  xmlns:ins     Sets the ins: prefix to an Inspector-specific namespace URI.

  ins:uid       Sets the basic viewer filename Inspector uses to find the viewer XUL file.
                For example, ins:uid="dom" leads to chrome://inspector/content/viewers/dom/dom.xul
                (ViewerRegistry.js#getEntryURL())

  ins:panels    This determines which DOM Inspector panels, by id, the viewer referenced is valid for.
                For example, ins:panels="bxObjectPanel bxObjPanel" means the panel id must be 
                bxObjectPanel or bxObjPanel.

  ins:description
                This sets a title for the viewer.

  ins:icon      This sets an icon for the viewer.  Currently unused.

  ins:filter    This determines which nodes (or in the case of JavaScript Object
                viewer, values), the viewer referenced is valid for.

                @param object - nsIDOMNode object (or in the case of JavaScript
                  Object viewer, JavaScript object).
                @param linkedViewer - linked viewer object.

                For example, ins:filter=
                "return object instanceof Components.interfaces.nsIDOMDocument;"
                is a JavaScript fragment ViewerRegistry.js uses to define a
                filter function if the panel's subject node is an instance of
                nsIDOMDocument.
