Hi Erik,

It already says something along these lines, so perhaps nothing more needs 
to be said after all.

I disagree with "each" here: a user may be typing fast in an input or 
text field, and committing data upon each keystroke may have negative 
performance implications.

This is particularly true if your XForms engine is distributed between 
client and server, where latency makes it even more impractical to send 
each and every keystroke to the server.

I think it would be reasonable to say that changes should be committed 
"from time to time", so as to give the user the perception that changes 
are taken into account immediately, but not necessarily upon each
