may also raise a special \exception{Fault} instance, used to signal
XML-RPC server errors, or \exception{ProtocolError} used to signal an
error in the HTTP/HTTPS transport layer.

+When passing strings, characters special to XML such as \samp{<},
+\samp{>}, and \samp{\&} will be automatically escaped. However, it's
+the caller's responsibility to ensure that the string is free of
+characters that aren't allowed in XML, such as the control characters
+with ASCII values between 0 and 31; failing to do this will result in
+an XML-RPC request that isn't well-formed XML. If you have to pass
+arbitrary strings via XML-RPC, use the \class{Binary} wrapper class
+described below.
