The document discusses how to use a JMS selector to filter messages on a JMS inbound endpoint in Mule. It provides an example Mule configuration that uses a JMS selector with an expression to filter for messages with a specific JMSCorrelationID property. The selector is set on the JMS inbound endpoint to filter the messages consumed from the queue.
