Re: Gateways

I think Mark was using "mismatches" in a different context.

How about adding an extra sentence instead?

<proposed tweak="jjm">
The outbound message may be different from the inbound message. 
Moreover, due to possible mismatches between the inbound and 
outbound interfaces, the message may have some or all of its 
meaning lost.
