-----------------------------------------
It returns an error when a feed.feedType is not specified.
Code for the service;
------------------------
function feed(){
var feed = new Feed();
//feed.feedType = "rss_2.0";
feed.title = "This is a test Feed";
feed.description = "This feed demonsrates the use of Feed host object to create
an RSS 2.0 feed.";
feed.link = "http://mooshup.com/rss20.xml";;
var result = feed.writeTo("test-created-rss-feed.xml");
}
Resulted error;

> Key: MASHUP-724
> URL: https://wso2.org/jira/browse/MASHUP-724
> Project: WSO2 Mashup Server
> Issue Type: Improvement
> Reporter: Jonathan Marsh
> Assignee: Tyrell Perera
> Fix For: 1.1
>
>
> Currently one cannot use a new Feed object without setting the feedType.
> Since many authors won't care what the version is (and most clients seem able
> to deal with multiple formats), can we default feedType to the most widely
> supported type?
