Jim has proposed a nice mapping between OPM and PML and I cannot tell 
how much I appreciate his effort. This is somehow what I call an 
intuitive mapping since some concepts seems to be very similar.

However, when one reviews these concepts, contrast them with their 
official definitions, and more importantly, try to use them to encode 
the provenance of some use cases, one sees that almost none of these 
mappings hold -- I will refer again to my tech report contrasting OPM 
and PML.

Many thanks,
