Re: ISSUE-95: New proposal for metamodel

I am trying to bring structure into the further discussion on the 
metamodel, as I am keen to finally make progress. We have two specific 
proposals on the table, unless someone else comes up with something very 
different and sufficiently worked out. I believe both Proposal 1 
(Arthur) and Proposal 3 (edited by myself) have a lot of overlap, and 
largely only differ in syntactic choices.

So I have tried to focus on 4 TOPICs and came up with sub-proposals that 
people could indicate their preferences for:

Thanks,
Holger
