XML document authoring with emacs nxml-mode

Start in the directory where the XML document lives.

Make a subdirectory i/:

mkdir i

Move your templates to that directory. For example:

mv proc step i

Add these lines to your .emacs file:

;; Define a command to insert a fragment from the i/ subdirectory.
;;
(defun insert-frag (name)
  "Like insert-file but prepends 'i/' to the path given."
  (interactive "MTemplate: ")
  (insert-file (concat "i/" name)))
;;
;; Bind the above command to C-c C-e.
;;
(global-set-key "\C-c\C-e" 'insert-frag)

To insert a template named F, use the key sequence “C-c C-e F”.
