We are limited in our ability to extend the service creation capabilities by the hard coded xml processing of the SARDeployer/ServiceCreator. With the jbossxb framework this can be externalized such that multiple formats of the jboss-service.xml descriptor can be supported and more sophisticated configuration can be applied at every level: attributes, interceptors, ctors, etc.

One context to which this applies is the prototype for adding interceptors to subdeployers discussed here:
http://www.jboss.org/index.html?module=bb&op=viewtopic&t=57296

The solution promoted there requires every deployer to declare an xmbean deployment with custom interceptors for the deployment interceptors. There should be some deployer specific format which allows for references to a shared interceptor stack along with a jbossxb schema that allows for more extensive configuration of the interceptors and deployers.
