Hi Loa,
if the WG decides to publish the document, then the Informational is the right track.

Appreciate authors to consider my comment on generalizing references to an Entropy Label in the tuple as <ELI, ELn>.

	Regards,

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
