SchemaResolverConfig MC bean and its usage in AS

[jaikiran]

I am trying to integrate EJB3.1 specific things in AS trunk. I noticed that there's a metadata-deployers-jboss-beans.xml with a SchemaResolverConfig MC bean:

<!-- The schema location to JBossXB binding class mappings. We specify the dtd/xsd name
    of the schema as the location to work with legacy dtd as well as namespace based
    documents.
    -->
   <bean name="SchemaResolverConfig"
      class="org.jboss.xb.binding.sunday.unmarshalling.SchemaResolverConfig">
      
      <!-- schemaLocation to JBossXBuilder binding classes -->
      <property name="bindingClassesByLocations">
         <map keyClass="java.lang.String" valueClass="java.lang.String">
    ....// trimmed
            
            <!-- EjbJarMetaData -->
            <entry>
               <key>ejb-jar</key>
               <value>org.jboss.metadata.ejb.spec.EjbJar20MetaData</value>
            </entry>
            <entry>

            <entry>
               <key>ejb-jar_3_0.xsd</key>
               <value>org.jboss.metadata.ejb.spec.EjbJar30MetaData</value>
            </entry>
            
            <!-- JBossMetaData -->
           ...//trimmed 
            <entry>
               <key>jboss_5_0.dtd</key>
               <value>org.jboss.metadata.ejb.jboss.JBoss50DTDMetaData</value>
            </entry>            
            <entry>
               <key>jboss_5_0.xsd</key>
               <value>org.jboss.metadata.ejb.jboss.JBoss50MetaData</value>

               <value>org.jboss.metadata.ejb.jboss.JBoss51MetaData</value>
            </entry>
            ... a lot more
   </bean>

How and where is this MC bean being used? I don't see its references in any other jboss-beans.xml. Is it mandatory to map a (new ejb-jar_3_1.xsd) xsd file to a class here?

This just adds location (=key) mapping to SchemaResolver, which is a singleton.

Afaik, you only need to add this if you allow less exact info in the xml to be mapped against this.

e.g. from the xsd file or via top level xml element

Yeah, that's how i have it in my local workspace too. But i was seeing if that can be avoided or done in a different way, since that file resides in the AS code base and is not specific to EJB3.
