24 | ;;; Commentary: | |
25 | ;; | |
26 | ;; A minor mode for use in decorating tags. | |
27 | ;; | |
28 | ;; There are two types of decorations that can be performed on a tag. | |
29 | ;; You can either highlight the full tag, or you can add an | |
30 | ;; independent decoration on some part of the tag body. | |
31 | ;; | |
32 | ;; For independent decoration in particular, managing them so that they | |
33 | ;; do not get corrupted is challenging. This major mode and | |
34 | ;; corresponding macros will make handling those types of decorations | |
35 | ;; easier. | |
