Note that I created a Hawiian keyboard layout (which produces a ʻokina (glottal stop) character with the single-quote key and is otherwise the same as the Maori layout. I am attaching the /usr/share/X11/xkb/rules/evdev.xml and the /usr/share/X11/xkb/symbols/us files which have had this layout enabled. This layout does work properly.
