91 /* This limit is artificially enforced, we do not depend on it any where.
92 * The reason it's still here is that the rules file format does not
93 * support multiple groups very well, and the rules shipped with
94 * xkeyboard-config (see rules/evdev) depend on this limit extensively.
95 * So just lifting this limit would cause problems for people who will use
96 * more than 4 layouts.
97 * TODO: Fix the group index syntax in the rules format, preferably in a
98 * backwards compatible way.
99 * See e.g. https://bugs.freedesktop.org/show_bug.cgi?id=14372
100 * Note: A limit on the number of groups we *do* depend on is imposed by
101 * the size of the xkb_layout_mask_t type (32). This is more than enough
