IBM have released a spec for a language that describes how web services may
be composed.
Unfortunately, the specification is only available as a
PDF -- evidently browser-accessible specifications are not a service that
IBM want to make available via the Web.
According to their announcement, WSFL describes composition of web
services:
Composition comes in two types: The first type allows to specify the
logic of a business process; the second type allows to define the mutual
exploitation of Web services of participants in a business process. A brief
concepts of composition sketch is provided in an introductory chapter of the
document. A detailed discussion of the metamodel behind composition follows.
The language proper is described and illustrated by code snippets, followed
by an XML schema of the language.
