;;; Commentary:
;; James Clarke's nxml-mode can be used for editing and validating
;; Muse-generated XML files. If you are in nxml-mode use the command
;; C-c C-s C-f to point to the schema in `contrib/muse.rnc', which
;; comes with Muse. Say yes if you are asked if you want to copy the
;; file to your location. C-c C-s C-a can then be used to reload the
;; schema if you make changes to the file.
;;; Contributors:
;; Peter K. Lee (saint AT corenova DOT com) made the initial
;; implementation of planner-publish.el, which was heavily borrowed
;; from.
;; Brad Collins (brad AT chenla DOT org) provided a Compact RelaxNG
;; schema.
