Events in XForms

Hi,

in §11.3 it says "Unless otherwise noted, the target node for all events is
the xform element".

I didn't find such a note, so e.g. an xforms-value-changing event is
targeted to the corresponding xform element. Does this mean that a form
control can't have an action (see §7.14.4.5) listening to these XForms
events ?

That would be surprising, so I think I must have misunderstood something...
If someone could enlighten me, thanks !
