Re: [mpls] working group last call on draft-ietf-mpls-spring-entropy-label

Greg,

(talking about the SHOULDs in Section 4 only)

I think what George (and Stewart) says is that since the document does
not use any MUST, SHALL or REQUIRED, it makes sense to publish it as an
Informational RFC.

However, it does not work to turn that argument around and say that an
Informational RFC can't use the normative language, it was doen for 
example in RFC 7412.

I think we should change it to Informational, but there is no need to
do anything to the SHOULDs in section 4.

/Loa
