5.2.1

line 124-126 This OPTIONAL
attribute contains a URI that

identifies the MPF to which
the message is assigned. The absence of this element indicates the

use of the default MPF.

 

This seems to imply that MPF
is always in play, which is not true, I think. Maybe a simple text fix can
resolve.
