wsdl namespace confusing

[Edward Chen]

In the book, 'J2EE� Web Services'

<definitions name="BookQuoteWS"
 targetNamespace="http://www.Monson-Haefel.com/jwsbook/BookQuote"
 xmlns:mh="http://www.Monson-Haefel.com/jwsbook/BookQuote"
 xmlns:soapbind="http://schemas.xmlsoap.org/wsdl/soap/"
 xmlns:xsd="http://www.w3.org/2001/XMLSchema"
 xmlns="http://schemas.xmlsoap.org/wsdl/">
 
<message name="GetBookPriceRequest">
  <part name="isbn" type="xsd:string" />
</message>
<message name="GetBookPriceResponse">
  <part name="price" type="xsd:float" />
</message>
 
.......
</definitions>

" message automatically take on the namespace specified by the targetNamespace attribute."

===================
My question is , why 'message' will use targetNamespace, not default namespace, 'xmlns="http://schemas.xmlsoap.org/wsdl/" ' ?

because, in my understanding, all elements should conform to defalut namespace, except those defined in this xml schema (that is , targetNamespace). But we didn't see 'message' defined in this xml schema, so , I think 'message' should use default namespace.

Could you please clarify my confusing ?

Thanks.
