Hi Alex,

Do you think that it would be useful if the draft also included the 
extra transient "-state" modules in an appendix (e.g. as per 
draft-dsdt-nmda-guidelines-01 section 2)?

Specifically, I'm thinking to help make the topology module fully usable 
by modules that augment it (e.g. by the TE modules if/when they adopt 
the NMDA conventions), until NMDA implementations before widely available.

Thanks,
Rob
