The first thing of note is that it ignores the recent URI IG publication,
by sticking to the classical view of URIs rather than the contemporary

Over time, the importance of this additional level of hierarchy seemed to
lessen; the view became that an individual scheme does not need to be cast
into one of a discrete set of URI types such as "URL", "URN", "URC", etc.
Web-identifer schemes are in general URI schemes; a given URI scheme may
define subspaces.

Also, you wrote:-

URNs are similar to URLs in that they are expected to resolve to a web

I think that you should put "URNs are similar to URLs in that they are
expected to identify a Web resource;" to reduce confusion.

As to the URP/URT distinction, I guess that "data:" is a URP scheme then,
yes? It beats the old "URL" definition that the RFC ascribes to it.

Overall, I like the draft.

You'll be wanting to do in plain text, then.

This reminds me a little of my URN proposal for exivars. That didn't get
very far, but is a valid principle, and one that RDF needs to be aware of:
if it decides to use URI/URI-views for identifying resources, then it
should fear the wrath of those those seek to encode it's idioms in new URI
