- * This class correctly handles normal llsd responses as well as llsd

- * For example, if given:
- * <code>{'response':[ i200, r3.4, {"foo":"bar"} ]}</code>
- * Would generate:
- * <code>
- * <?xml version="1.0"?>
- * <methodResponse><params><param><array><data>

- * @class LLFilterSD2XMLRPCRequest
- * @brief Filter from serialized LLSD to an XMLRPC method call
- *
- * This class will accept any kind of serialized LLSD object, but you
- * probably want to have an array on the outer boundary since this
- * object will interpret each element in the top level LLSD as a
- * parameter into the xmlrpc spec.
- *
- * For example, you would represent 3 params as:
- * <code>
- * {'method'='foo', 'parameter':[i200, r3.4, {"foo":"bar"}]}
- * </code>
- * To generate:
- * <code>
- * <?xml version="1.0"?>
- * <methodCall><params>
- * <param><value><int>200</int></value></param>
- * <param><value><double>3.4</double></value></param>
- * <param><value><struct><member>
- * <name>foo</name><value><string>bar</string></value></member>
- * </struct></value></param>
- * </params></methodCall>
- *
- * This class will accept 2 different kinds of encodings. The first
- * just an array of params as long as you specify the method in the
- * constructor. It will also accept a structured data in the form:
- * {'method':'$method_name', 'parameter':[...] } In the latter form, the
- * encoded 'method' will be used regardless of the construction of the
- * object, and the 'parameter' will be used as parameter to the call.
