One point I keep noticing but do not think I have raised before is

      units mbps;
      description
        "Bandwidth in Mbps,

I have known systems fail because one party was using mbps, another
Mbps, so seeing a mix of the two, as here, raises a flag for me.  I note
that
draft-ietf-teas-yang-te-types
has
       units "Mbps";
which I prefer - if they really mean Mbps and not mbps; I have my
doubts! - but then
 draft-ietf-l2sm-l2vpn-service-model-10
has
        units "mbps";
        default "10";  description
          "LACP speed. By default, the lacp speed is 10Mbps.";

Perhaps in the context of MPLS there is no ambiguity but it would be
nice to have consistency at least within an I-D.
