Unfortunately, I have not received this message from Gregg and got it from the
Todd's response.
I am curious, what API we are talking about in here? Is this a SOA forum or
OO forum? I believe that "Creating more variations for the client to deal with
is" MUCH better thing in service-orientated architecture than telling a
client/consumer "that it is not proper to make that request/call at that
time." Otherwise, we are loosing the sense of SERVICE in general.
