Common Filter
A common filter, specified with org.eclipse.ui.navigator.navigatorContent/commonFilter defines a filter that is controllable by the user in the view. The filter definition contains an id, a description that describes the filter, a description that describes what is filtered out, and the conditions (using core expressions) that identify objects the filter suppresses.

The common filter is bound to the view using the viewerContentBinding element of the viewer configuration.
