<h2>Behavior</h2>
Use this rule to test for and prevent invalid cyclic connections.
The behavior should be to look for cyclic connections that may be created if the given
source and target plugs are connected.
Whether such cyclic connections (if found) are allowed depends on the type of elements that are connected.
By default, all cyclic connections are allowed.(c) SAP AG 2003-2006. All rights reserved.
