Topic	XmlBlaster sends the subscription id in the qos arguments of an update
Des cription	Sometimes when a client receives an update message, she wants to know which of its subscriptions caused this update. You may retrieve the subscription id in the qos argument of the update using the <subscribe id=''> tag. This is is the same which she got as return value of the former subscribe() invocation. Update messages which where sent as PtP messages (and therefore where not subscribed) are marked with <subscribe id='__subId:PtP'>
Example Java	<qos> <subscribe id='__subId:2'/> <!-- The same id which you got returned from your previous subscribe() --> </qos>
Configure	NOTE: Configuration parameters are specified on command line (-someValue 17) or in the xmlBlaster.properties file (someValue=17). See requirement "util.property" for details. Columns named Impl tells you if the feature is implemented. Columns named Hot tells you if the configuration is changeable in hot operation.
