Subject: RE: [ebxml-msg] MS v1.05
Remember, what we are trying to decide is: Is Message Order required in the
Core or optional. Are we going to require that *every* MSH support Message
Order?
No one is suggesting that Message Order goes away.

All
I hope you all understand and realize that I was using a simplified example,
I certainly did not intend for it to be a model to design from :-) that
said, I can think of several applications where in-order delivery would be
useful and if I had it available to me I would certainly use it, that's just
me.

Brad

I'd never design a system that depended upon order and certainly
not something like this (cancel last order without explicitly
referencing WHICH order I meant) but maybe that's just me.
IMO, you have to expect things will go awry. You always need to
be prepared for the unexpected ("no one expected the Spanish
Inquisition!" ;-)
Cheers,
Chris
