In reading over the spec, I'm left with a few questions both about intent 
and about eventual implementation.

Is it the intention of this group to define all the elements you would need 
to create a complete, full featured user interface in the XForms User 
Interface? I'm wondering whether we could create really thin XForms clients 
for all types of three tier systems where the client only needed to 
represent the View.

It looks like the spec makes assumptions about the environment it is 
operating in. Will there be support for things like new windows or dialog 
boxes, for example? Would you be able to do something like transform XForms 
into equivalent XUL or UIML, meaning that the features of each of these 
would be present to some degree in XForms?

Another question I have is whether there is any need to incorporate support 
for binding between XML data elements and UI elements using XBL 
(http://www.w3.org/TR/xbl/). Perhaps there is no need since XPaths by 
themselves can do the job, but I'm not sure.

Finally, Is there any intention to separate the input instance data from 
the output instance data, so that there could be two potentially different 
schemas for each? In other words, the XML tree you receive from a web 
service to populate your UI is not necessarily the same tree you want to 
send on Submit.
