+/// If there is data but it cannot be successfully parsed,
+/// an error is also returned.  If successfully parsed,
+/// the output LLSD object, out_llsd, is written with the
+/// result and true is returned.
+///
+/// @arg	response	Response object as returned in
+///						in an HttpHandler onCompleted() callback.
+/// @arg	log			If true, LLSD parser will emit errors
+///						as LL_INFOS-level messages as it parses.
+///						Otherwise, it *should* be a quiet parse.
+/// @arg	out_llsd	Output LLSD object written only upon
+///						successful parse of the response object.
