pseudo class only serves the purpose to browse code not installed in the image. We will remove them soon and replace them by Ring meta model entities. All the tools should be able to use Ring entity since they are polymorphic to runtime entities. For example, no need for a special browser just a normal one using the same interface to manipulate in image, remote or on disc changeset like or MC entities RIght now pseudo class are just a hack to cover the lack of a decent code meta model.
