I have logged this JIRA issue, which I hope is self-explanatory:
http://java.net/jira/browse/JMS_SPEC-50

Any objections?

In the JMS Specification 1.1, Chapter 1.3 "What Is Required by JMS" says:

"Providers of JMS point-to-point functionality are not required to provide publish/subscribe functionality and vice versa."

However Java EE 6 in Section EE.2.7.8 "Java™ Message Service (JMS)" says

"The Java Message Service is a standard API for messaging that supports reliable point-to-point messaging as well as the
publish-subscribe model. This specification requires a JMS provider that implements both point-to-point messaging as
well as publish-subscribe messaging."

It is proposed to change the JMS specification to bring it in to line with Java EE, and make it mandatory for a
standalone JMS provider to implement both point-to-point messaging (Queues) and publish-subscribe messaging (Topics).
