I've done that sort of thing, but without the XML.

It would be nice for there to be a mechanism for getting access to a 
blocks object handle for "helper" code, for doing things like calling
  getter methods so that "helper" python code can do things based on 
calls to an objects "parametric" methods (that is, non-data-path).
