WSDD: Would service level config override ?

[ajax chelsea]

Hi all:
    I want to know whether Individual Service Configuration can override the <globalConfiguration>? for example:

<globalConfiguration>
    ...
    <parameter name="
sendMultiRefs" value="true"/>
    ...
</globalConfiguration>

then 

<service name=...>
 <parameter name="className" value="
org.apache.mystuff.MyService"/>
 <parameter name="sendMultiRefs" value="false"/>
 <operation ... />

 <typeMapping ... />  
 <beanMapping ... />  
</service>

Will it work? Thanks.
