             Summary: update transformers API to better support chaining and recursion
                 Key: AS7-6321
                 URL: https://issues.jboss.org/browse/AS7-6321
             Project: Application Server 7
          Issue Type: Task
          Components: Domain Management
            Reporter: Emanuel Muckenhuber
            Assignee: Emanuel Muckenhuber
            Priority: Critical
             Fix For: 7.2.0.CR1


The current transformation APIs have no support for chaining multiple transformers, which is mainly problematic for recursive resource transformations and alias operations.

We need to review the core concepts and update them if necessary before 7.2 to properly support this.

This may also involve updating the registration process and moving all transformers into a specific DomainExtension (or at least remove the deprecation of the current ExtensionContext.isRegisterTransformers()).
