So taking a step back, perhaps there is a YANG language question at the
heart of this discussion.  I think we're seeing cases where the same
data model is useful in multiple cases/places.  The example I like to
use (although I know others disagree with the example) is the case of
PE/CE config information, where some of the exact same information may
end up on the CE and PE devices as well as the L3 service model.  In
this case we'd like a core model to be "included" (or "linked") into two
larger models.  Importantly, I'm referring to doing this as part of
model definition - not at server/device run time.  This is important for
the pre-provisioning case. 

It is my understanding that there is no way to really do this in a
general and extensible way (including allowing for augmentations)
today.  If there was such support, I do think we'd be saying that we'd
like the existing models to support this mechanism rather than our
current proposal of being relocated .
