Intel patented XML based GUI specification / generation?

Intel is listed as having patent # 6941521, filed 3/29/02, granted 9/6/05.
Method for dynamically generating a user interface from XML-based documents

Basically, describe a UI in XML, and have it "rendered" as an actual GUI, perhaps in SWING or AWT, .net, etc.  And I had thought that you'd also need to make references to event handler routines, perhaps in some other class file.

I'm not a lawyer, and I don't know the timeline of other such efforts, so no slight at Intel intended, but I had thought this was a well established idea prior to '02 ?

For example, isn't XUL mostly that?  In my notes I had:

• XUL starting page and XUL Planet
•  Luxor XUL
• CookSwing
• JFCML JFC / Swing / XML Markup language
• SwiXAT here and here
•  SwiXml
•  Jelly Swing, XML based UI builder (defunct)

Comments welcome, maybe there's some detail of it that's different, or maybe in '02 it was really new.
