why are the WS-Addressing WSDL binding elements capitalized?

In the past wsdl and it's well defined extensions (soap, http, mime) have 
all use lower case element names.  Is there a reason why the wsaw 
element's use a leading upper case?   Perhaps it's a minor point ... but 
things would look consitent if wsaw:UsingAddressing wsd redefined to be 
wsaw:usingAddressing.

<binding name="reservationSOAPBinding" 
    interface="tns:reservationInterface"
    type="http://www.w3.org/2006/01/wsdl/soap"
    wsoap:protocol="http://www.w3.org/2003/05/soap/bindings/HTTP">
  <wsaw:UsingAddressing wsdl:required="true" />
  <operation ref="tns:opCheckAvailability"
      wsoap:mep="http://www.w3.org/2003/05/soap/mep/request-response" />
  <fault ref="tns:invalidDataFault" wsoap:code="soap:Sender" />
</binding>


thanks
