proposed replacement text for 3.2

The normative outline for the Optimized Mime Serialization policy 
assertion is:

        <mtomp:MTOM [wsp:Optional] [wsp:Optional] .../>

The following describes additional constraints on the outline 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 MUST NOT include the wsp:Ignorable attribute in 
its [children] property.
