   This just has to be the world's worst way of indicating equality....

   Whatever happened to variables? (I know, but its a rhetorical question)

Because we're analyzing processes as sets of execution traces, we need
a way to say: 

   For every instance of composite process C,
   consisting of subprocesses P1 and P2, 
       the value of the Output property of the instance of
             P1 belonging to C 
     = the value of the Input property of the instance of 
             P2 belonging to C.

It appears that there is no way to say this in DAML+OIL, although we'd
be glad to hear of any.  Hence we had to make up a nonstandard
notation with meaning to DAML-S processors beyond what a DAML+OIL
processor would infer.
