so, if you want to figure out what filter
was used that allowed the message to be produced/delivered/sent/whatever_verb
dereference the subscription EPR and examine the metadata associated with
the Subscription. Although you could do this to figure out topic
informatoin too, it is slightly less obvious, in certain cases, if the
topic filter is specified and it is /*/, it is useful to know which
topic(s) the message was published on.

Right ... so you can leave that out if you want. The
question is, can you put anything else in if you want? I had thought
there was open content, but there doesn't seem to be.
The other question is to what extent the core needs to talk about topics
at all, or if you prefer, to what extent are topics "just another
filter"?

+1 to Sanjay.
We had the notion of filter previously (we called it selector) but did
not choose to add it to the "metadata" in the Notify message.
I don't see that anything has changed to compel us to rethink this
bit.
So what's so special about topics? Also, wasn't that decision taken
prior to making topics optional?
