CustomInterceptor configuration is incomplete and buggy

Infinispan 5.2 schema allows to declare a custom interceptor with properties as follows:

<customInterceptors>
<interceptor position="LAST" class="com.group.awms.is.resource.dao.infinispan.interceptor.ApplicationInterceptor">
<properties>
<property name="cacheActivityName" value="activity" />
</properties>
</interceptor>
</customInterceptors>

Problem is that method parseInterceptor of class Parser52 does not expect any content for interceptors and the following exception is raised:

Message: Unexpected element '

{urn:infinispan:config:5.2}

The Parser class is not in sync with the schema.
