Arrrgh. From my original point to its polar opposite in six steps (quite a
tangency!). Would anyone care to give a declarative definition of semantic
equivalence in the general case? Can that be done except, as here, by
prescribing canonical processes in order to constrain their potential outcomes?
But isn't that the centrally-controlled converse of what we hope for from web
[nocap] services? Isn't the point of WS to offer best-of-breed expert
functionality in all of its exquisite idiosyncrasy so that its uncompromised
power can be harnessed into customized workflows? But if the processes are
canonical to such a degree that we can speak of their outcomes as semantically
equivalent, what's the point of using a web-available process rather than
building your own and avoiding all the problems of security and of semantic
