Plugin GUI: How to link system types?

Hi All,

within a plugin's GUI descriptor it is possible to link to component procedures directly, without defining a plan for these explicitly. This is done using the compProcedureRun tag in XML.

Is it possible, using this method, to link to the methods of an abstract super component, i.e. one that is extended by other components. This would be the equivalent to calling on a systemType within the XML code.
