[jboss-as7-dev] Add Notification support to the domain management API

[Jeff Mesnil]

I understand why the doc was not clear: I forgot to publish the draft and the public version was the outdated one. Stupid me!

The doc is now correct: https://community.jboss.org/wiki/AddNotificationSupportToTheDomainManagementAPI
