Hi, Balázs, and thanks for the quick replies on both documents.

For both documents, the data-plane-framework draft has terminology, at
least, that needs to be understood in order to fully understand these
documents.  That makes the data-plane-framework draft a normative
reference -- it doesn't matter that data-plane-framework is
informational... it matters that unless you understand the terminology
in data-plane-framework you're missing something with respect to the
detnet-mpls docs.

Please re-word the text in the document to make it more
understandable.  As I say, I can't parse the quoted phrase at all.  I
don't know what "non-skip zero" means, and I think the word "what" is
not the right word, and doesn't make sense there.
