Well, yes, but that takes all the fun out of it.  You seem to be
saying that human developers, given enough clear information about web
services, can write any desired program for interacting with web
services.  That's certainly true.  The more interesting question (to
me, anyway) is whether there is a point in "generality space" where it
pays people to describe web services formally enough that automated
agents can write the programs, or at least play a role in writing
them.  The descriptions would have to be written without detailed
knowledge of what program was going to be required, which seems to
indicate that the notation should be neutral and general-purpose.
Such notations tend to look like logic of some kind.

Of course, the answer to the "interesting question" may well be No.
