The XML representation of a message is a plain text file, so it is generally much larger than an equivalentrepresentation in another format (such as delimited, binary, or custom formats).
This paper, using the method of differential equation, proves some characters properties of basic elementary function, and then concludes an equivalentrepresentation about basic elementary function.
