+;;; Commentary:
+
+;; This enables the use of the character names defined in the Unicode
+;; Standard.  The use of the names can be controlled on a per-block
+;; basis, so as both to reduce memory usage and loading time,
+;; and to make completion work better.
+;; The main entry point is `nxml-enable-unicode-char-name-sets'.  Typically,
+;; this is added to `nxml-mode-hook' (rng-auto.el does this already).
+;; To customize the blocks for which names are used
