Topic XmlBlaster allows to qualify messages as read only
Des
cription		 Using the QOS attribute readonly allows to mark a published message as read only (you may think of a final/const message). The first published message is respected, later published messages are rejected. The XmlBlasterException errorCode user.publish.readonly is thrown.
Example
Java 
      
      <qos>
        <topic readonly='true'/> 
         <!-- A final/const message which may not be changed with further updates -->
         <!-- Default is Read/Write -->
      </qos>
