    I didn't say that. I said that XML is not an XHTML document. It's 
similar to how a square is a rectangle, but a rectangle is not a square.

    I think you're forgetting the WF2 clients that support XHTML. Also, 
I believe Mozilla, Opera and Safari all support XHTML, so why would 
employees of these companies define a standard that requires them to 
treat HTML and XHTML differently?
