	This project began based on code from the 2 projects below,
	and still contains some original code. The licenses of both must be respected.

	XML-RPC for PHP

	SOAP for PHP
	by Victor Zou (C) 2000-2001 <victor@gigaideas.com.cn>

	/*  changelog:
	2001-07-04
	- abstract type system to support either 1999 or 2001 schema (arg, typing still needs much
	solidification.)
	- implemented proxy support, based on sample code from miles lott <milos@speakeasy.net>
	- much general cleanup of code & cleaned out what was left of original xml-rpc/gigaideas code
	- implemented a transport argument into send() that allows you to specify different transports
	(assuming you have implemented the function, and added it to the conditional statement in send()
	- abstracted the determination of charset in Content-type header
	2001-07-5
	- fixed more weird type/namespace issues
