I have not been able to get those axes working either. I've looked briefly at the implementation of `sxml:preceding`, and it's unclear to me how it could even work.
Since `txpath` appears to work, I'd stick with that. I'm not sure why it's deprecated in favor of `sxpath`. Since, AFAICT, we're just packaging that library (i.e. not developing it) and its development appears to have stopped, I don't expect `txpath` to go anywhere.
