    Oops. Somehow I never notices that...

    It's a category of extensible markup languages used for constructing 
user interfaces. It's not supposed to be too specific, as it describes 
more than one language. Then again, you should know this, since you 
invented the term:

    If this is the case, I'd prefer that it be called "Web Apps 1.0". 
Calling part of something that already is a language a "language" is 
just confusing.

    So generally, there are no namespaces unless you're using a mixed 
XML document.

    Hmm. Makes sense, considering the nature of WF2.

    So, as long as we use markup that fits into the HTML4 model, there's 
nothing really stopping us from using markup from an XUIL, correct?
