Dear Authors, et.al,
I've got a question, or several of them, about data models of MPLS label
and MPLS label stack element (LSE). I ahve not followed the discussions and
apologize if these already were considered, discussed.
In the Routing Types document I've found that only MPLS label being modeled
but not the MPLS LSE. As result, models that use rt-types:mpls-label, e.g.
YANG DAta Model for MPLS Static LSPs, defines outgoing labels not as array
of LSEs but as array (leaf-list) of MPLS labels. In the latter document I
don't see how TTL and Traffic Class (TC) are presented for each of labels
in the array. Hence my questions:

   - should there be data model of MPLS LSE in rt-types (it does have TTL
   and TC but separately);
   - should data model of Static MPLS LSP use MPLS LSE model rather than
   model of only 20 bit-long label.

Appreciate you comments.

Regards,
Greg
