Changed so that knot references in knotted ties never have a uniqueness constraint, which occurred for example in 1-1-1 ties (representing ternary relationships involving a knot). Since the idea of the knot is that the cardinality of its identifier is smaller than those referencing it, it can never have a uniqueness constraint.
