Query: Demaq: A Foundation for Declarative XML Message Processing   This paper gives an overview of Demaq, an XML message processing system
operating on the foundation of transactional XML message queues. We focus on
the syntax and semantics of its fully declarative, rule-based application
language and demonstrate our message-based programming paradigm in the context
of a case study. Further, we discuss optimization opportunities for executing
Demaq programs.
