RE: Required Fields

There is already a binding attribute to specify a required field--no need for a new child element. It is up to the xforms implementation to decide how to enforce that in user interface. One approach is as you describe; although, like the other responder, most users will not like this rigid approach!

An interesting approach is that taken by ASP.NET webforms' validation controls (and probably other dynamic HTML solutions). If the user enters a value and then clears the field, then upon leaving the field the alert appears immediately as dynamic HTML near the field. However, the form does not prevent the user from tabbing out and giving focus to the next field.
