Re: [xml-dev] [off-topic] xtext -- encoding declarations for text

http://www.topologi.com/resources/xtext.html reminds me of -*- in EMACS,
which I remember using in 1979; i.e.
  ;;; -*- Mode: Lisp -*-
  /* -*- Mode: C; Comment-Column: 72 */

A more recent reference:
http://www.gnu.org/manual/emacs-21.2/html_mono/emacs.html#SEC486

I note that the examples don't include perl or python, which on some
operating systems requires that the first line begin with "#!".
