Hi Burcu, Nice to hear from you and it is good you are active on the list. Yes that is true, but as to my understanding, the ASN.1 in Annex B is not part of the DSP.

However, the DISP has also a bind operation on top of that (7.4.1 of X.525), while hierarchical operational bindings (clause 24 of X.518) does not have a separate bind. Why this difference?
