These are excellent questions.  It does perhaps go a bit out of the scope
of the list, so we've been talking about this offlist.  If anyone is
interested in the discussion, or even wants to take it to another list,
let me know :-)

I wanted to offer a brief summary on the list since that question had been
asked here --

First, I have never used XML/XSLT, and I find all this fascinating :-)
Thanks to Cees for bringing it to my attention.

But it sounds like XML/XSLT in this context were designed to tackle a
slightly different issue.  OpenThought is able to update a portion of the
screen, without reloading any other part of the page.  Cees explained to
me that with XML/XSLT, the page would be regenerated each time a new XML
packet was received.

So really, you could use XML/XSLT for templating, and OpenThought on top
of that for dynamic screen updates.  OpenThought goes a step further than
that and offers:

  * Compatability with 4.0 browsers
  * The ability to send JavaScript from the server to the browser and have it
  immediatly executed
  * You can load a new page while maintaining the session, without using
  cookies or url parameters (and this should also work when using
  OpenThought together with XML/XSLT)
  * And of course, the OpenThought examples are all written using
  CGI::App! :-)

I'd be happy to go into detail with what OpenThought supports.  If it's
somehow related to OpenThought functioning with CGI::App, feel free to ask
here... otherwise maybe you should message me offlist :-)

Have a good one!
  -Eric
