Servlet definition
A servlet is a component that takes a request and a context as input, and provides a response as output. The request is represented by an element srv:request and a sequence of zero or more request bodies. The context is represented by an element srv:application and an element srv:servlet. The response is represented by an element srv:response and a sequence of zero or more response bodies.
A servlet can be implemented using one of various technologies. Each kind of servlet has its own rules for receiving requests and providing responses. The available servlet kinds are:
- an XPath function (provided by an XQuery library module, a stylesheet, or any other implementation-specific means);
- an XSLT named template;
- an XQuery main module;
- an XSLT stylesheet;
- an XProc pipeline (and a step type?).
