How about submitting sources to

  http://bzr.savannah.gnu.org/r/emacs/elpa/

In this case package become available in

  http://elpa.gnu.org/

Or ever to Emacs distro?

Why this to do? Because of nxml-mode it is important for Emacs to have
rnc-mode. Personally I write some own .rnc files and read a lot of SVG/XHTML
etc .rnc files in Emacs.

Also this is very stable package (as remarked in original discussion) so
additional maintenance is not required and this is big argument for inclusion
to Emacs or GNU elpa.

And I don't know how long Tom will be interested in maintaining rnc-mode. With
Emacs developers community this mode will be more living then with single
maintainer... Any further maintenance can be done with bug submission for
anyone.

That my suggestion. And I know that pushing mode to Emacs is hard work.
It may require David Rosenborg permission or something similar...

I use original rnc-mode.el (from home page) without modifications in Emacs
23/24 for long time (but use only basic features - indentation and
highlighting)... It have such header:

  ;;   A major mode for editing RELAX NG Compact syntax.
  ;;   Version: 1.0b3
  ;;   Date: 2002-12-05

  ;;   Copyright (c) 2002, Pantor Engineering AB
  ;;   All rights reserved.

So I surprised that it didn't work for Tom.

I checkout Tom's git sources and found only 2 difference in:

  (defun rnc-make-regexp-choice (operands)

and

  (defun rnc-electric-brace (arg)

which use non-existing functions in Emacs 23/24.

So seems that I have in some way broken code highlighting. And I avoid to use
'electric' features in all modes...

But my Emacs don't produce errors in *Message* buffer for my use cases.
