Implemented a new resource="file:///:self" syntax to explicitly generate pass through pipeline specifications because of URLRewrite filter transformation into a regular URLRewrite server in eXist 2; had to do that because as far as I could observe <forward url="a/b/c"/> where c is not an xquery script  causes a new call to controller.xql to rewrite URL "/a/b/c", if the purpose is to pass through to directly serve c then the controller.xql must explicitly return an ignore or an empty URL rewrite pipeline specification (which is what fie:///:self is doing); the consequence is that on eXist-2 the mapping must explicitly map all the "static" model resources which are directly generated from files (or database resources I suppose).
