Namespace

To add event information associated to RSS items, first you have to declare a namespace, as additional XML nodes in RSS documents must be prefixed by a namespace.

In your RSS document, just declare the namespace, for example ev:

<rss version="2.0"
  xmlns:ev="http://zoggy.frama.io/erssical/doc-event.html#">
   ...
</rss>
Elements

The following elements can be added under the <item>..</item> node.

<ev:audience>

Who can attend to this event, specified as free text. Example:

<ev:audience>Software developers and researchers</ev:audience>
<ev:endDate>

When the event ends, in RFC#822 format. Example:

<ev:endDate>Thu, 25 Apr 2013 17:00:00 +0100</ev:endDate>
<ev:keywords>

Keywords, listed in <item>..</item> subnodes. Example:
