Oops, my mind is now too used to the H-W rewrite I'm working on - I
meant the "All" constraint, not "Required".

Also, I've just done a test, and even if an All constraint were added,
there would still be no errors, because nothing is sent at all for a
multi-select element when no items are selected.
