Derivation Valid (Restriction, Complex) (potential erratum?)

In the constraint "Derivation Valid (Restriction, Complex)"

2.1.3 [Definition:]  Let the effective value constraint of an attribute use
be its {value constraint}, if present, otherwise its {attribute
declaration}'s {value constraint} . Then one of the following must be true:
2.1.3.1 B's ·effective value constraint· is ·absent· or default.
2.1.3.2 R's ·effective value constraint· is fixed with the same string as
B's.


2.1.3.2 mentions "the same string as B's". Shouldn't it be either the same
"actual value" or the same "canonical representation"? (I think actual
value is more proper.)
