  * This pattern expects the following meta tags to be available in the page to get the necessary configuration
  * - patterns-push-url containing a url pointing to a message queue server. Eg. ws://127.0.0.1:15674/ws
- * - patterns-push-exchange-base-name containing a text prefix. It will append _event and _notification to that prefix and attempt to contact these two message exchanges.
+ * - patterns-push-exchange containing the exchange nanem to subscribe to.
  * - patterns-push-filter containing a topic filter including dot-seperated namespaces and wildcards. A commonly used filter value would be the currently logged in user. This will subscribe only to updates for this specific user.
  * - patterns-push-login containing the name of a read only user on the message queue server used to connect.
  * - patterns-push-password containing the password of a read only user on the message queue server used to connect.
