The following table lists all of the DRM classes. The DRM class name is a hyperlink to the DRM class definition. The entries in column one that are italicized represent abstract DRM classes. The entries in column two are hyperlinks to the UML diagram for that DRM class. The entries in column three are hyperlinks to the location of that DRM class on the various UML composite diagrams referenced in Annex A, with the entry in bold being considered the primary location for that class in the UML composite diagrams.
Navigation among the various components is possible using hyperlinks that are contained in the UML diagrams and in each DRM class specification page:
