Quite right:  The description doesn't match the specified derivation.
I can't speak for the WG--I suspect there will be a quick survey of
implementations to see if they commonly accept an optional leading
'+'.  However, since unsigned integer allows the sign(s), if I had
to I would guess that the others will too.

In any case, I'm sure the WG will make a decision one way or the other.
