RFC 7012, "Information Model for IP Flow Information Export (IPFIX)", September 2013Source of RFC: ipfix (ops)

Section 7.2 says:
The specification of new MPLS label types MUST be published using a well-established and persistent publication medium.
It should say:
This paragraph envisaged that a new RFC be written to specify new label types in the mplsTopLabelType sub-registry.
Since the publication of RFC7012, IANA has added 16 other IPFIX IE sub-registries, none of which have the same requirement. See https://www.iana.org/assignments/ipfix/ipfix.xhtml
Publication in IANA's IPFIX registry should provide a clear and persistent definition. New IPFIX MPLS label type specifications should not be singled out to require persistent publication of an additional document.
