How to configure jboss-deployment-structure.xml in EAR files to force Weld to use JSF Version 1.2?

Issue

• If Weld is not forced to use JSF Version 1.2, it picks the 2.1 Version (despite the declaration of Mojarra-1.2 in web.xml) and the following error occurs:

• If the following Weld modules in JBoss are modified to use JSF Version 1.2, the error does not appear and everything works fine:

"jboss-eap-6.1.0/modules/system/layers/base/org/jboss/as/weld/main/module.xml"
"jboss-eap-6.1.0/modules/system/layers/base/org/jboss/weld/core/main/module.xml"

  <dependencies>
     ...
     <module name="javax.faces.api" slot="1.2"/>
     ...
  </dependencies>

• But we get stuck if we try to achieve the same with "META-INF/jboss-deployment-structure.xml". The error appears again:

<jboss-deployment-structure>
    <deployment>
        <exclusions>
            <module name="javax.faces.api"/>
            <module name="com.sun.jsf-impl"/>
        </exclusions>
        <dependencies>
            <module name="javax.faces.api" slot="1.2"/>
            <module name="com.sun.jsf-impl" slot="1.2"/>
        </dependencies>
    </deployment>
</jboss-deployment-structure>

• How to use the "jboss-deployment-structure.xml" to achieve the same effect as modifying the module dependency definitions?
• Is there a "Per Application" solution available, because changing the whole JBoss instance to use JSF 1.2 will cause problems with our JSF 2.0 Applications.
