Hi Huub, think we agree, see inline.

But shouldn't the client layer be able to determine whether the fault cause is in its own layer or in the server layer? This is similar to the notification server trail failure to its client layer. So in fact the same notification can be used for both cases. MB> Agree, I had made that assumption, but it should be an explicit statement (in the NM requirements?).
