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
view:-

[[[
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.
]]] - http://www.w3.org/TR/uri-clarification/

Also, you wrote:-

[[[
URNs are similar to URLs in that they are expected to resolve to a web
resource;
]]]

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
schemes.

Cheers,
