+0.5 - I agree in principle, would need to see the spec text to
understand if we lose anything by doing that. I don't expect that we would.

+0 - I think it would be very strange to have almost the entire document
be non-normative and have two normative appendices that define the
entire language. That said, it might be nice to see the spec text in
order to understand what the change would look like.

I don't know of many other W3C specs that do this, do you? This would
also have the down-side that I couldn't just go to the section on "IRIs"
to get a high-level understanding of the normative requirements of IRIs.
That said, there isn't much normative text in there, so maybe this
change would be fine.

-0.3 I think it would be strange to not introduce the terminology early
in the document. If I understand your proposed change, the reader would
effectively start reading about terminology that they've never seen before.

+1 in principle, need to see the spec text.

One minor thing we need to discuss: The proper protocol of merging your
changes in with the document. From what I remember, you're not an RDF WG
member? Since that's the case, you're probably going to have to do some
W3C song-and-dance (sending something to RDF Comments, maybe as a patch
request)? We just need to make sure you're covered by the IP policy for
the RDF WG. It shouldn't stop you from doing a pull request via github,
just know that the request may be parked until we figure out the best
way to get the IP Policy to apply to you.

Do you have a preference to how we should handle this? Statement by you
on RDF Comments? Patch request to RDF Comments? Invited Expert application?
