Getting additional keyword information from item Xml?

Question

I have a very generic "GetItemXml" template building block that basically reads the current item being rendered and outputs the item's xml to the delivery tier.

Component component = (Component)engine.GetObject(package.GetByName(Package.ComponentName));
output = package.CreateXmlDocumentItem(
           ContentType.Xml,component.ToXml(XmlFormat.R6Native, XmlSections.All)
                                                                .OwnerDocument);

This outputs the xml correctly, but keyword fields are output like this:

<ContentCategory>tridion</ContentCategory>
<ContentCategory>tridion2009</ContentCategory>

Is there any way - short of controlling the XML output myself - to ask Tridion to include additional information in the XML like an xlink:href to the keyword ID?

You just need to Load component with proper LoadFlags, like this:

Component component = (Component)engine.GetObject(package.GetByName(Package.ComponentName));
component.Load(LoadFlags.KeywordXlinks);
output = package.CreateXmlDocumentItem(
    ContentType.Xml,component.ToXml(XmlFormat.R6Native, XmlSections.All).OwnerDocument);

It will look like this:

<keyword xlink:href="tcm:2-83-1024" xlink:title="b" 
         xmlns:xlink="http://www.w3.org/1999/xlink">b</keyword>
