Note from the charset reviewer:

I understand that a new registration form will be sent to this list, 
addressing comments, and that no action from the charset reviewer is 
appropriate yet.

I recommend using the registration form in RFC 2978 as at least part of the 
document. If you want publication of the whole document, the best thing may 
be to publish this as an RFC; this allows for including much more 
explanatory material.
The first step is then to publish the document as an internet-draft.
