I wasn't sure where it should go, but I added a 'requirements' section 
in the wiki which describes the current hierarchy in our model here:
 https://forge.gridforum.org/sf/wiki/do/viewPage/projects.nml-wg/wiki/Requirements

I also added a section on the ps network element identifiers to 
https://forge.gridforum.org/sf/wiki/do/viewPage/projects.nml-wg/wiki/Naming 

Cheers,
