While on the surface the combination of software components that adhere to associated standards should lead to rapid and successful system implementation. However, issues can arise when integrating independently defined software subsystems. Here conflicts are discussed that arose when integrating elements from the Web Services Architecture (WSA) led by the World Wide Web Consortium (W3C), specifically publish/subscribe communication and service security. Unfortunately, the various standard components are seldom completely independent, and when separate components are jointly deployed unanticipated interactions sometimes cause significant problems at implementation time.
