Hi Murray,

Please find the diff:
https://author-tools.ietf.org/diff?doc_1=draft-ietf-babel-rtt-extension-05&doc_2=draft-ietf-babel-rtt-extension-06

Looks like the technical issue converged and the text is fixed.
Are there any remaining showstoppers?

You're absolutely right.  The first paragraph is normative, while the second paragraph is merely an implementation suggestion.  I'll remove all normative language from the second paragraph.
