Re: [mpls] Question on draft-ietf-mpls-rfc4379bis-09.txt

One other point I raised was that spring-lsp refers throughout to
Downstream Mapping TLV
and not to
Downstream Detailed Mapping TLV

Mustapha assumed that these should all be changed.  I am unsure about
this - is spring-lsp expected to work with Downstream Mapping TLV as
specified in RFC4379?  If not, then I think that spring-lsp should spell
that out.

Either way, the wording changes to spring-lsp need some thought since
Downstream Mapping TLV does not have subTLVs and Downstream Detailed
Mapping TLV does.
