   ==== How to send custom XML as payload of a method call::
   
   Unfortunately, at the time the XML-RPC spec was designed, support
  
positive.code: The __minimum supported__ PHP version is 5.3.
  
  If you wish to use HTTPS or HTTP 1.1 to communicate with remote servers, or to use NTLM authentication, you need the
      "curl" extension compiled into your PHP installation.
  
  If you wish to receive XML-RPC requests or responses in any other character set than US-ASCII, ISO-8859-1 or UTF-8, you
      will need the "mbstring" extension compiled into your PHP installation.
  
  The "xmlrpc" native extension is not required to be compiled into your PHP installation, but if it is, there will be no
      interference with the operation of this library.
  
  
  
negative.code: 
  * improved: the function `wrap_php_function()` now can be used to wrap closures (it is now a method btw)
  
  * improved: all _wrap_something()_ functions now return a closure by default instead of a function name
  
  * improved: debug messages are not html-escaped any more when executing from the command line
