To this extent, the PEP sends decision requests to a PDP whenever access to a resource in the scope of the PEP is requested and receives responses containing the access decision from the PDP. While the structure and content of the decision requests and responses are specified in XACML, protocols for sending these requests and responses are not defined by this standard. Other standards such as SAML have to be employed for this purpose. The decision request is accompanied by all required information concerning the requestor (subject), the resource access is requested for, the action requested to be performed on the resource, and the context (environment) in which the access request occurs.

These papers address the issue of verifying compliance of programs with security policies and, therefore, their scope is comparable with the scope of consideration adopted in this book, albeit from a theoretical view. Language-based techniques provide means for analysis or monitoring supported by properties or semantics of the particular programming or scripting language. Though the work concerned with these techniques relates to programming languages in general and is not particularly related to Web services or mobile code, the results of this work may also be extended thereto.

0 by OMG. Though the existence of several parallel standards aiming at the same goal, in general, adversely affect the very purpose of standardisation, the different standards at least have some obvious commonalities, as all languages except of BPMN are script-based using XML47 and facilitate the composition of business processes by invocation of Web services and definition of the communication with other parties (in particular human participants) involved in a business process. Among these standards, BPMN plays a special role since it provides a graphical notation for representing business processes to be specified and may be best compared with UML as a modelling tool.
