Yes, it's undocumented and buggy (uses a keysym where it should be using a keycode). We should probably just rip the code out rather than fixing it, since you can instead do xmodmap -l or xmodmap +l Caps_Lock Note that this doesn't, strictly speaking, switch the key between up/down and toggle, as was possible in X10 (but which was a complete crock). It switches the key between being used as the Lock modifier and not being as a modifier. A side-effect on various systems will be to switch the toggle behavior.
