Michael,

Sorry for my slow response. I had a look at your latest version now, and I
think it looks good from a general YANG pov.

Yes, if what you want is to describe protocol messages, sx:structure would be a
good way to package this.

What aspect of this solution do you consider less than optimal? That's not
quite obvious to me.
If any of this causes problems with SID generation, I'm afraid that's not my
territory. :-)

Thanks for putting this in concrete and easily accessible form, i.e. as
compilable YANG modules on github.
