Summary: web\(\pi\) is a recent process calculus that has been inspired by the emerging Web Services technologies. In this paper we explore the expressivity of web\(\pi\) by discussing two case studies. The first case study is about the formal semantics of the transactional construct of BPEL – the scope construct. The second case study is about a standard pattern of Web Services composition – the speculative parallelism – that allows several alternative activities to be started; only the first one that completes is taken into account while the other ones are aborted.
