Correct, and the only normative reference in W3C's HTML is the URL Standard by WhatWG:
  https://www.w3.org/TR/html/references.html#biblio-url <https://www.w3.org/TR/html/references.html#biblio-url>

That's where I disagree: the URL reference we agreed upon does obsolete URI or IRI, and it isn't just about "link" on the web.
So when, exactly, would we need to use "URI" or "IRI", except perhaps in an explanatory note alongside the [URL] reference?

URNs were mentioned several times in call discussions on IRC.

My email was to debunk stuff like "URI = URN + URL", or "URN is not a URL", or "URL is only for a “link” on the web", which is untrue with the normative reference we agreed to use.
