Missing primitive specific operation for <fanOutPoint>
TS-0004 clauses 7.4.14.3.2, 7.4.14.3.3 and 7.4.14.3.4 contain the sentence
Primitive specific operation after Recv-6.2 "Check existence of the addressed resource" and before Recv-6.3 "Check authorization of the Originator".
In R4 everything is ok, as we introduced an operation. The sentence above is followed by If the Primitive Profile Identifier parameter is present in the request, the Receiver shall return a response primitive with a Response Status Code indicating "OPERATION_NOT_ALLOWED" error.
However in R2 and R3 no primitive operation is given.
Also in 7.4.14.3.5 (including R4) the corresponding paragraph for Delete looks strange. What it says is the following:
Primitive specific operation after Recv-6.2 "Check existence of the addressed resource" and Recv-6.3 "Check authorization of the Originator": The To parameter consists of the URI of the group resource plus a suffix consisting of /fopt or /fopt/ plus any additional appended relative address.
Again there is no explicit additional processing mentioned.
