Question regarding :read-only and XForms...

   My understand of :read-only is that it was originally created for
XForms to provide a way for styling read-only controls, since their is
no "read-only" attribute directly on the XForms element in question.
However, if the read-only XForms control is in a user-editable context,
such as inside an <html:div contenteditable> element, or if the
containing document is being edited, therefore making all content
user-editable, wouldn't the element in question become unselectable
without changing the markup?
