10.2.4 of RFC 3261 indicates that 200 OK should contain current binding. Although 200 OK should have Expires=0 in this case.

No more bindings are stores in the registrar for this sip user. The user agent starts a deregistration procedure (i.e. REGISTER with Expires=0). How shall the registrar build the 200 OK response assuming no binding is left? I guess the 200 OK MUST include a Contact header, even though no binding is left, right?
