Support for Authorization Modules

[barramundi]

From the jbosssx project, I found what I need to create is a module like the ones under org.jboss.security.authorization.modules & org.jboss.security.authorization.modules.web/ejb

However, I did not find this package under JBoss Application Server version 4.0.5 GA 's jbosssx.jar

Is the roadmap for supporting these authorization modules just for JBoss AS 5.x only?
or is there a plan to support it with 4.0.x ?
or it is already supported with 4.0.5 ?

Thanks.

Got some reply. 4.0.x does not support Authorization Modules
