1. Introduction

Generic Alerts is a way to extend headlines to allow functionality similar to .NET Alerts.

2. Requirements

The motivations for this document are:

3. Use Cases

3.1 Generic Alert message

Generic Alerts extend headline messages to specify such things as a logo (32x32 png) and url to goto when the alert is clicked:

Example 1. Generic alert message

<message to='user@domain.com' from='domain.com' type='headline' id='alert1'>
  <subject>Auction Alert</subject>
  <body>You have been outbid!</body>
  <alert xmlns='http://jabber.org/protocol/alert'>
    <logo>http://www.auction.com/alert.png</logo>
    <url>http://www.auction.com/item?1292192</url>
  </alert>
</message>

4. Implementation Notes

The following guidelines may assist client developers.

5. Security Considerations

None.

6. IANA Considerations

No IANA interaction required.

7. XMPP Registrar Considerations

The XMPP Registrar [1] will need to register the new namespace of "http://jabber.org/protocol/alert".
