The impression I've gotten from Dean is that you're rarely, if ever,
going to try to use "<" on a partial ordering. Is this correct?

Most programmers only work with totally ordered spaces and so probably
won't come across this distinction. Java doesn't even have support for
partially ordered spaces. (Is there a language that does?)

There, that ought to do it. ;)
