Err... I actually don't think it's all that ambiguous.  The
directoryString syntax as a minimum length requirement.  If
violated, it should cause invalidAttributeSyntax.  If an
attribute type is defined with a maximun size, then a
server may return constraintViolation.  I say may, not
should, as maximum in LDAP are just hints.

I offer a less confusing example to demonstrate the
difference meanings of these resultCodes:  If the directoryString
value provided contains octets which are form an invalid
UTF-8 encoding, an invalidAttributeTypeSyntax would be
an appropriate error to return.  If two syntaxically valid
values were provided but the attribute type was defined
as SINGLE-VALUE, then constraintViolation would be returned.
