jboss-web.xml is not well formed EAP5.1

Issue

• We have a WAR file with the following schema declaration contained in WEB-INF/jboss-web.xml:

<?xml version="1.0" encoding="UTF-8"?>
    <jboss-web xmlns="http://www.jboss.com/xml/ns/javaee"  
               xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
               xsi:schemaLocation="http://www.jboss.com/xml/ns/javaee http://www.jboss.org/j2ee/schema/jboss-web_5_1.xsd"   >
    <security-domain>java:/jaas/somename</security-domain>
    <context-root>/someContextRoot</context-root>
</jboss-web>

• Deploying the WAR results in the following error:

ERROR [AbstractKernelController] Error installing to Parse: name=vfszip:/C:/jboss/eap5.1.0/jboss-eap-5.1/jboss-as/server/all/deploy/Some.ear/ state=PreParse mode=Manual requiredState=Parse org.jboss.deployers.spi.DeploymentException: Error creating managed object for vfszip:/C:/jboss/eap5.1.0/jboss-eap-5.1/jboss-as/server/all/deploy/Some.ear/SomeWebApp.war/
