Ah, I see I'm taking UA too narrowly, and now understand the
"UI" sense that you and others were referring to.

But I also sense that you recognize the importance to us that
in a UA where one might reasonably be able to
extract/cut-n-paste/whatever a chunk from a page, that that
chunk would be available in XML form.
As far as I've been able to think the problem through,
such a capability goes a long way towards interoperability.

Thanks for the clarifications.
