Document/Literal Wrapped Style/Use

Hello Friends
IBM article here
http://www-128.ibm.com/developerworks/webservices/library/ws-whichwsdl/

explains that Document /Literal wrapped style/use is the best as it generates the same soap message as RPC/literal the only difference being
in the way the types section is defined for D/L W and D/L does not have type which leads to an advantage of D/L W over D/L.

Now I did not understand correctly the below statement mentioned as an advantage in the D/L w please can you explain.

"Everything that appears in the soap:body is defined by the schema, so you can easily validate this message. "

Thanks

Everything that appears in the soap:body is defined by the schema, so you can easily validate this message.

This means that you can have a XML schema which defines the contents under soap:body and any XML validator can be used to validate this message. This is also true for document/literal.

Hello Deepak
Thanks for your reply,
If RPC/Literal as well produces the same SOAP Envelop with myMethod element
inside it why cant we have a XML schema which defines the contents under soap:body and any XML validator can be used to validate this message.
What is different in that case?
Thanks

in case of RPC/literal myMethod is the method name and thus is not part of the XML schema
