      This is the XML Schema for the application client 6
      deployment descriptor.  The deployment descriptor must
      be named "META-INF/application-client.xml" in the
      application client's jar file.  All application client
      deployment descriptors must indicate the application
      client schema by using the Java EE namespace:
      
      http://java.sun.com/xml/ns/javaee
      
      and indicate the version of the schema by
      using the version element as shown below:
      
      <application-client xmlns="http://java.sun.com/xml/ns/javaee"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
      	http://java.sun.com/xml/ns/javaee/application-client_6.xsd"
      version="6">
      ...
      </application-client>
      
      The instance documents may indicate the published version of
      the schema using the xsi:schemaLocation attribute for Java EE
      namespace with the following location:
      
      http://java.sun.com/xml/ns/javaee/application-client_6.xsd

      The following conventions apply to all Java EE
      deployment descriptor elements unless indicated otherwise.
      
      - In elements that specify a pathname to a file within the
      same JAR file, relative filenames (i.e., those not
      starting with "/") are considered relative to the root of
      the JAR file's namespace.  Absolute filenames (i.e., those
      starting with "/") also specify names in the root of the
      JAR file's namespace.  In general, relative names are
      preferred.  The exception is .war files where absolute
      names are preferred for consistency with the Servlet API.
