take 2 proposed replacement text for 3.2

The normative pseudo schema for the Optimized Mime Serialization policy 
assertion is: 

        <mtomp:MTOM wsp:Optional? .../> 

The following describes additional constraints on the pseudo schema listed 
above: 

/mtomp:MTOM 

    A policy assertion that specifies that MTOM [MTOM] MUST be used in 
messages sent to the Web service. It also specifies that responses from 
the Web service MUST be optimized using MTOM [MTOM], i.e. that the 
messages must be sent using the application/xop+xml mime type. 

/mtomp:MTOM/@wsp:Optional="true" 

    Per WS-Policy [WS-Policy], this is compact notation for two policy 
alternatives, one with and one without the assertion. This indicates that 
the behavior indicated by the assertion is optional, specifically that 
non-MTOM-encoded exchanges are also supported by the endpoint. 

/mtomp:MTOM/@any

    This is an extensibility mechanism to allow additional attributes to 
be added to the element. 

The MTOM policy assertion element information item MUST NOT include the 
wsp:Ignorable attribute in its [attributes] property with a value of 
'true'.
