Clarification about <filled> execution in FIA

Hi,

In FIA it has not been clearly specified if execution of selected chain of
<filled> elements in document order should continue or not in the event of
an error conditions like <throw> or error.badfetch inside a currently
executing <filled>.

It is mentioned in FIA , "event handler selection starts in the scope of the
<filled>, which could be an input item or the form itself."

After an appropriate event handler is found and executed where should the
execution resume?

a) Should it be next <filled> in the document order?

b) Or should it continue within the same <filled> element where event
occurred?

c) Or Should it completly abort the execution of remaining <filled> elements
and continue with the Select Phase.

I would think a), but wants to get others opinion on interpretation of
specification.
