Hi,
I think this is relevant to the question,
Why is the filter coupled to a stream?
There is nothing in the draft (or the design) that makes this
assumption.
From the minutes of the Montreal interim meeting:
"h) Notification suppression filtering is data-model and
stream dependent."
My interpretation of this is that a filter might be (might need to be)
designed to apply to a particular (type of) stream. If, for example,
the SIP community developed a new stream format, then some
SIP-specific filters might only make protocol-sense with that stream.
Therefore, one might want to define the relevant stream as part of the
namedProfile.
