XML-RPC is simple spec that describes how to invoke a remote operation using XML over HTTP. Laszlo XML-RPC is part of Laszlo RPC and shares many of the same APIs and concepts. Laszlo RPC includes SOAP and JavaRPC. For more information on XML-RPC, go to XML-RPC.com
Most Laszlo RPC objects like JavaRPC and SOAP will set function stubs in the proxy property during load based on methods described by a class (for JavaRPC) or on a service description (using a WSDL in SOAP). Remotecall declarations refer to these function stubs and any remotecalls not pointing to a function stub that doesn't exist will generate an error/warning. In <xmlrpc>, function stubs are created based on remotecall declarations. Note that XML-RPC use dot notation for their operation names. Because that will conflict with the view system's notation, it's suggested that remotecalls are explictly named.
