Hi,

(I found the "HTML" comment very funny, btw. :)

I'm thinking of something much more heavy-duty.  Like, I want to support a complex user
interface that has many complex widgets, with flexible event wiring, that must make accesses
to back end data.  Something like the UI for a Bloomberg Box, or Microsoft Encarta.

This in itself is "easy", and typically done by having a platform-specific UI that retrieves
domain objects from a datastore/business logic middle tier.

More interesting and challenging would be to make the UI/backend split "higher up".  Do all
the layout work on the backend, and just send a platform-independent description of the UI
over the wire.

And -that- is what's led me to look for a Component Markup Language.
