[soa-rm-ra] Re: first complete draft of SOA testing

[Rex Brooks <rexb@starbourne.com>]

Hi Ken,

I had a similar concern with the term mockup, so it might be more 
clear to use a compound term like "prototype service interface."

It also strikes me that it might also be good to draw a distinction 
between inter- and intra-enterprise  or ecosystem and enterprise 
testing.

Cheers,
Rex
