Steve, I'm just on the 7th page of the Double R Grammar paper so I'm rushing ideas here, but it is interesting to see how Multinet, while taking roots in Conceptual Dependency Theory / Case Grammar, and taking the concepts it talks about as mental realities, lands quite close to the philosophy of Double R Grammar (which defines itself in opposition to the above) by insisting on "grounding concepts in lexicon".
