Hi Ismail,

Ah, yes, I tested some days ago and wondered what was wrong. I do not 
know if it is good to split rng-auto.el, but here are some notes:
- The autoload has been moved somewhere else.

- Some variables are set in rgn-auto. Maybe these just can be moved to 
the defvars?
  (setq rng-preferred-prefix-alist-default ...)
  (setq rng-schema-loader-alist '(("rnc" . rng-c-load-schema)))

- There are some add-hook calls, maybe they can be moved to 
nxml-mode.el? (The first one of these starts validation.):
  (add-hook 'nxml-mode-hook 'rng-nxml-mode-init)
  (add-hook 'nxml-mode-hook 'nxml-enable-unicode-char-name-sets)

- I have no idea what to do with the auto-coding stuff. Does not that 
have to be loaded before nxml-mode is loaded since it is used when 
reading files?
  (require 'nxml-enc)
  ;; Install our own `set-auto-coding-function'.
  (nxml-start-auto-coding)
