Hi Roland,

Thanks for the prompt response.

I guess there are several issues here, as you imply. In some scenarios it 
might be nice to "submit" (or should that be "save"?) a part-completed form 
to a server data store of some sort. Other scenarios would be local saving to 
submit the full data at some later time.

One of the issues that seems relevant if submitting to a server data store is 
the ability to keep the identity of the user bound to the identity of the 
data. And, of course, if XForms normally validates the data, a mechanism to 
indicate to the XForms processor that the (part) data isn't yet ready for 
validation.

For local saving there would need to be consideration of what a "form" is, in 
respect of the need to associate the correct visual appearance of the form 
while, presumably, overriding the default instance markup - so that the 
"saved data" constitutes the initial data to be copied to the "instance 
data".

Is saving / suspend and resume firmly on the agenda for XForms 2.0?
