Advantages and Disadvantages of Using the Document/Literal Messaging Mode
Using the document/literal mode of messaging has the following advantages:
You do not have to specify the data type in the SOAP message.
You can use any XML validator program to validate the message.
The document/literal mode is better suited for asynchronous processing because it does not use method calls.
Using the document/literal mode of messaging has the following limitations:
The WSDL document becomes a little more complicated.
Message processing is difficult because there is no element within the SOAP message that directly corresponds to the operation specified in the WSDL document that is being called.
Message dispatching is difficult or impossible because the operation name in the SOAP message is lost.
