|

;;; 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
