If we do vote to include the SC, we then have to open up the RM to everything else that follows which means that it won't be a RM, it will be architecture.

Duane,

This is an idea that I see you have been pushing very hard almost from the start of our TC, yet I believe some of us are perplexed as to why introduction of a service consumer into an RM is against the notion of RM. Can you please clarify for us?

I would like to call for a vote on this too to put it to bed for once an
all.� My assertion = If I architect something with a service, a consumer
does not have to be present for it to be "service oriented".�� Nor do
messages, networks, signals, pings, security, encryption etc etc.�� This
is much the same as stating that a "message" does not have to be sent in
order for it to be a "message".� It can exist with or without being
transmitted.
If we do go the way of the service provider and service consumer, this
could be done in an illustrative (non-normative) manner in the RM or
(and I favor this idea) as part of a reference architecture.� If we do
vote to include the SC, we then have to open up the RM to everything
else that follows which means that it won't be a RM, it will be
architecture.
I had hoped we could gain consensus on this and avoid a vote however I
feel a vote may be inevitable.
BTW - has anyone else noticed that the list is very slow today? It took
5 hours for my last message to come back to me via this list?
