UML14 — Missing mapping for directed constraint

Summary: p. 17 NG "For two graphical symbols (such as two classes or two associations):
The constraint is shown as a dashed arrow from one element to the other
element labeled by the constraint string (in braces). The direction of the
arrow is relevant information within the constraint."

and on p. 18:

"A constraint string attached to a dashed arrow maps into a constraint
attached to the two elements corresponding to the symbols connected by the
arrow."

Since the direction of the arrow is relevant: how is this direction mapped?

Fixed in UML 1.3
