Didn't this recently change by issuing erratum 31.2 Rigorously Define 
Non-relevant Form Control 
(http://www.w3.org/2006/03/REC-xforms-20060314-errata.html#E31b)? It 
explicitly states that "A critical part of this erratum is that XForms 
action handlers for events on the form control are disabled when the 
control is non-relevant" this the of course repeated in the 'Changed 
specification wording' section "When a form control becomes
it must receive event xforms-disabled and then the XForms action
that are listening for events on the non-relevant form control must be 
disabled."  Or am I reading this incorrectly?
