I'm trying to build an RSS reader in VB.net.
I have created a class for RssItems, such as the following,
PUBLIC CLASS RssItem
   Public Author as String
   Public PubDate as Date
   Public Description as Description
   Public GUID as String
   Public IsPermaLink as Boolean
END CLASS

The above is purely abstract.
I need to be able to serialize the above object as follows,

<RssItem>
   <Author>....</Author>
   <PubDate>....</PubDate>
   <Description>....</Description>
   <GUID IsPermaLink="false">....</GUID>
</RssItem>

I'm able to serialize the object into an xml string similar to the above,
but without the IsPermalink as an attribute of GUID.
Basically i need to be able to configure the IsPermaLink to be an attribute
of the GUID element.
