3.10 Specifying the transfer coding

Description[top]

Every Binding Message Reference component MAY indicate which transfer codings, as defined in section 3.6 of [RFC2616], are available for this particular message.

The HTTP binding provides a mechanism for indicating a default value at the Binding component and Binding Operation levels.

If no value is specified, no claim is being made.

Relationship to WSDL Component Model[top]

The HTTP binding specification adds the following property to the WSDL component model (as defined in [WSDL-PART1]):

• {http transfer coding}, a string value to the Binding Message Reference component.

XML Representation[top]

<definitions >
  <binding name="xs:NCName" interface="xs:QName"? type="xs:anyURI"
           whttp:defaultTransferCoding="xs:string"? >
    <operation location="xs:anyURI"?
               whttp:defaultTransferCoding="xs:string" ? >
      <input messageLabel="xs:NCName"? 
             whttp:transferCoding="xs:string"? />

      <output messageLabel="xs:NCName"?
              whttp:transferCoding="xs:string"? />
    </operation>
  </binding>
</definitions>

The XML representation for specifying the default transfer coding is an OPTIONAL attribute information item for the binding element information item or binding's child operation element information items with the following Infoset properties:

• A [local name] of defaultTransferCoding

• A [namespace name] of http://www.w3.org/2004/08/wsdl/http

• A type of wsdls:string

• No default value

The XML representation for specifying the transfer coding is an OPTIONAL attribute information item with the following Infoset properties:
