These attributes allow the user to request that specific portions of an archive should be ignored. These attributes are meant to be attached to a "RIB archive node". For instance, they could be used to allow the same RIB archive to be used for a beauty pass (using the various Hypershade materials it contains) and in an occlusion pass, where the "Ignore Archived Surface Shaders" attribute would be turned on and an occlusion shader would be attached to the RIB archive node. See RIB Archive Node.
