XML_RPC2_Client must maintain a function namespace as clean as possible. As such whenever possible, methods that may be usefull to subclasses but shouldn't be defined in XML_RPC2 because of namespace pollution are defined here.
void printPostRequestDebugInformation( mixed $result)
void printPreParseDebugInfo( string $request, string $body)
boolean testMethodName( string $methodName)
NB : The '___' at the end of the method name is to avoid collisions with XMLRPC __call()
