Business Process Execution Language for Web Services (BPEL4WS) is an evolving OASIS standard for defining business processes that orchestrate the execution of Web Services. The language provides for the definition of variables, which are accessed and modified by interacting with Web Services or via activities that provide for the modification of variables. Scopes are a means to control the parallel access to variables. In some cases however, this approach is not flexible enough. It is suggested that lock and release activities are being added that provide for very granular control of the execution of parallel paths.
