Hi Ron,

I think this new SRv6 endpoint behavior is very useful to connect an 
SRv6 island and an SR-MPLS island. I have two comments.

In this draft, you introduced the End.DTM as a new "segment type", but 
according to draft-ietf-spring-srv6-network-programming draft I think 
this should be "endpoint behavior".

Section.1 says "The arguments determine MPLS-label stack contents and 
Transport Class of the MPLS Tunnel." I was interested in this feature, 
but there is no detailed description in Section.4. Could you elaborate 
on this feature in the future version? I also want to clarify the 
meaning of "Transport Class of the MPLS Tunnel".

Thanks,
Takuya
