Can WSDL have both Document style and RPC Style ?

[lavnish lalchandani]

Hi
As per my knowledge in a WSDL
A message part may declare either a type attribute or an element attribute, but not both. Which to use depends on the kind of messaging you're doing. If you're using RPC-style messaging, the part elements must use the type attribute; if you're using document-style messaging, the part elements must use the element attribute

Is a WSDL like this valid ?

<!-- message elements describe the input and output parameters -->
<message name="GetBookPriceRequest">
<part name="isbn" type="xsd:string" />
</message>
<message name="GetBookPriceResponse">
<part name="price" type="xsd:float" />
</message>
<message name="InvalidArgumentFault">
<part name="error_message" element="mh:InvalidIsbnFaultDetail" />
</message>
</definitions>

here GetBookPriceRequest & GetBookPriceResponse seems to be in RPC style and Fault seems to be in document style
