	XMLCALL	- The calling convention to use for all calls across the
				"library boundary."	This will default to cdecl, and
				try really hard to tell the compiler that's what we
				want.

	XMLIMPORT	- Whatever magic is needed to note that a function is
				to be imported from a dynamically loaded library
				(.dll, .so, or .sl, depending on your platform).

	The XMLCALL macro was added in Expat 1.95.7.	The only one which is
	expected to be directly useful in client code is XMLCALL.

	Note that on at least some Unix versions, the Expat library must be
	compiled with the cdecl calling convention as the default since
	system headers may assume the cdecl convention.

	2. No character may require more than 4 bytes to encode.

		0xFFFF, (i.e., characters that would be encoded by surrogates in
		UTF-16 are	not allowed).	Note that this restriction doesn't
		apply to the built-in support for UTF-8 and UTF-16.
