Re: generic sort based on attribute names

OK,
This is the recursive stylesheet I have, to handle a generic XML.
How does the thing you explained with the 'e' fit here.

It will convert an input like this:
<root>
	<e b="bb" y="yy">
		<node x="123" a="123"/>
		<node x="999" a="999" b="999"/>
	</e>
	<e z="zz" a="aa"/>
</root>

to this:
<root>
	<e a="aa" z="zz"/>
	<e b="bb" y="yy">
		<node a="999" b="999" x="999"/>
		<node a="123" x="123"/>
	</e>
</root>

e.g. when the 'root' element is matched, the 'sortkey' variable contains:
<e>by</e>
<e>az</e>
