This is possible for just Internet Explorer and can be added to 
XSLTForms for it only.

For other browsers, there is a known trick consisting in sending all the 
data to the server then back to the client with a specific header 
forcing the client to display the save as dialog. Because of the 
cross-domain constraint, this cannot be done by a local HTTP server if 
the initial form comes from another HTTP server. It can be solved using 
a local proxy instead !

Yes, local applications are not dead and I developed a tiny HTTP server 
(named tXs) just for that because browsers don't treat local files with 
less security constraints. I, now, think that it would be even better to 
transform this program as a proxy...

No, it is not yet implemented because it's not very easy with HTML forms 
and Javascript and because XForms recommendation says that the content 
can be embedded in an instance, not just the selected filename. Another 
server page could do the trick... or a local proxy (did I say that 
already ? ;-) ) ...
