RE: How to forward instance data between forms ?

Thank you very much.
The example is very close to my needs : I want to
split a commercial transaction over various screens,
using a wizard-like display. 

I think the "file:" mode is limited, though :
1 - Can you give the user the ability to choose the
directory where the instance data will be saved ? c:
is a little rough.
2 - On the other hand, the file URI pointing to a
server is not very safe from a security point of vue.

Back to the wizard-like display, which is as I was
saying, exactly the kind of process I would like to
implement, I'm unconfortable with the fact that
different views of the same user instance data should
be coded in the same xml document, through
xforms:switch and xforms:case elements. I would
definitely prefer the ability to split among different
xml documents, sharing instance data as session data.

Thank you very much anyway.
The provided example does help me a lot.
