I think this would be useful as for certain conditions I just want a whole section to be readonly and I currently find myself having to go through it field by field. Even worse when I later add a new column to that section I might forget to set the behaviour rule for it. A readonly attribute at section level would a) imply the section is Visible (as opposed to any of the other three current attributes) b) override editable or required at field level, but not override hidden at field level
