Yes, there is no size constraint on the sequence.  It can be
empty. Semantically, I believe such a request should be regarded
as a request to "touch" the object.  That is, the operational attributes
such as modifiersName and modifyTimestamp, of the target should be
updated.  It is noted as well that such a request might fail for
a variety of reasons (e.g., schema violation, access control).

Though not detailed specifically, I believe the above semantic is
consistent with RFC 4511 and, for DAP, X.511.  That is, the
above semantic doesn't conflict with the RFC 4511 or, for DAP,
X.511.
