    <p>Enables developers to spend less time recoding and testing when the business policy changes.</p>
    <p>The Business Rules service minimizes your code changes by keeping business logic separate from application logic.</p>
    <p><b>Node Configuration</b></p>
    <ul>
    <li> Create and Bind a Business Rules service instance on this Node-RED App</li>
    <li> Deploy some Decisions Services</li>
    <li> Select the Decision Service to be executed and click on Done</li>
    <li> In input, wire your Business Rules node with a valid Json or Xml payload (use the test tool to help you)</li>
    <li> In output, wire your Business Rules node with the node that will use the response of Decision Service execution request done by this node</li>
    </ul>

    <p><b>Node input</b></p>
    <ul>
    <li><code>msg.payload</code> : a string representing a valid XML or JSON payload matching the selected Decision Service in the node configuration.</li>
    </ul>
    <p><b>Node output</b></p>
    <ul>
    <li><code>msg.payload</code> : the decision corresponding the input data, returned either in XML or JSON as detected in the input.</li>
    </ul>
