It might be easier for readers and responders if you separated your
questions into different messages. Anyhow:

<ASIDE>Java shared class variables *are* global variables. But that
doesn't really have anything to do with XSL.</ASIDE>

Yes, but more generally, any variable whose namespace is the global one
is a global variable. Since JavaScript has many tricks for manipulating
namespaces, this does not just mean variables defined in a
<define-script> block. And of course any variable *reached through* a
global variable is also global.

Global functions are global variables in JavaScript.

<SCRIPT>
function a(){
	return 5;
}
document.writeln( a() )

function b(){
	return 10;
}
a = b 

document.writeln( a() )
</SCRIPT>
