I can do without this argument getting in this thread ;-)

So little? Reusing UI presentation and logic, including behaviour hooks
for interaction logic to output to different UI formats such as Swing
and HTML is lots more that "so little" and I have not seen any contender
to UIML yet.

XML is a format with hierarchical relationship semantics build-in while
non-hierarchical relationships can be described easily. And it's a text
format, not a proprietery representation you cannot send over to your
partner without tons of documentation and code for him to be able to use it.

Verbose and unreadable? It's by far the more efficient mechanism I have
seen in action, it works without compiling enything and it's
possibilities are unlimited. It also utilizes browser capabilities to
the maximum. I have nothing more to ask of when it comes to web app UIs.
I can come up with reusable custom elements representing widjets that
work instantly, removing the mess of JavaScript code and it's binding to
elements in the page. I can even come up with custom events, while
anonumous content is something I could never even hope for.
And it's just JavaScript code in XML; the latter provides all the bindings.

House of cards? Nope, not me.
