  We finished adding an example for GSS_WrapEx with AES128-CTS-HMAC-SHA1-96 in [MS-KILE]. The attached PDF document is the newly added section(4.3) of the [MS-KILE] document.

  We really appreciate your suggestion.   Please let us know if you have further questions regarding this subject.

We believe that the diagrams imply interaction between elements and without detailed notes they are subject to multiple interpretation and hence confusion.    We believe that as a matter of providing deterministic documentation, we would prefer to provide specific examples.

A visual description of how the RRC interacts with the AEAD behaviour and the subsequent placement of the trailer in the header will be critical.
