+ Artifacts may be shared by plans.
+ Sharing occurs when a plan is deployed which references an artifact that was previously deployed or is a child artifact
+ of a plan that was previously deployed.
+ Sharing also occurs when an artifact is deployed which is already a child of a deployed plan, but in this case the shared
+ artifact may <emphasis>not</emphasis> appear as a top-level artifact, for example, in the Admin Console, in the shell,
+ and in JMX.

+ Sharing is taken into account when artifacts are stopped.
+ A shared artifact is stopped only when all the artifacts referencing the shared artifact have been stopped
+ and, if the shared artifact was deployed in its own right, the artifact itself has been stopped.
