Migration Guide 4.8. Missing link to Java EE specification

Link: https://access.stage.redhat.com/documentation/en/red-hat-jboss-enterprise-application-platform/version-7.0.beta/migration-guide/#migrate_jms_deployment_descriptors

In documentation a reference to Java EE specification is mentioned, but there is no link to the referenced version of the specification. It may be difficult for customers to find referenced document.
