This paper discusses the compatibility issue between policies of Web services, which could refrain the automatic composition of these Web services from smoothly progressing. Policies regulate/constrain the functioning of Web services at three levels identified by business, behavior, and privacy. Because independent Web services collaborate with one another in order to satisfy users' needs, their respective policies could be in contradiction. This could lead to conflicts and exceptions at run-time unless these contradictions are as a first step, detected and then, fixed. In this paper, WSPL is the language to specify policies of Web services.
