But that's not who registering an URI scheme works. Check the relevant 
RFCs. Essentially you register the *URI* scheme, and get IRIs based on 
the mapping rules defined in RFC 3987.

I haven't checked yet.

It would be helpful if you didn't abuse the IETF ID submission system as 
local storage, and only submitted new drafts when you want community 
review. Is now a good moment to read it?

The RFC reference is immutable. Just paste the content in your source 
file, and change the anchor attribute value.

You can't register an IRI scheme. (Unless I missed something).

Nope. (See above)

You need to state how you want to encode non-ASCII characters. "See 
RFC3987" goes into the right direction but really isn't sufficient. 
Please see RFC 4395, Section 2.6:

"2.6. Internationalization and Character Encoding

    When describing URI schemes in which (some of) the elements of the
    URI are actually representations of human-readable text, care should
    be taken not to introduce unnecessary variety in the ways in which
    characters are encoded into octets and then into URI characters; see
    RFC 3987 [6] and Section 2.5 of RFC 3986 [5] for guidelines.  If URIs
    of a scheme contain any text fields, the scheme definition MUST
    describe the ways in which characters are encoded, and any
    compatibility issues with IRIs of the scheme."
