The configuration in deployment.xml just proxies through to the app server code, we do not do anything with it. The main reason for doing this within the AS 4 deployer was probably a consequence of the app server's restriction in only allowing a single deployer per deployment, so each deployer was responsible for handling this. This is no longer necessary in AS 5 so we should follow the standard mechanism, using the jboss-classloader.xml.
