>> Has the ability to perform its functionality synchronously or asynchronously
To explain synchronous and asynchronous communication, I use a telephone
example. If someone answers when you call, that synchronous. If no one answers
but you leave voicemail, that's asynchronous.
SOAP supports synchronous and asynchronous messaging. Using RPC-style
messaging, communication is synchronous and the service provider and consumer
maintain state. Document-style SOAP messaging (XML document in the payload)
supports asynchronous messaging because you can encapsulate state information in
a document.
