I was hoping someone might be able to help me with a sort problem.  I
would like to sort on a presorted node in the same stylesheet.

I would like to sort this (NOTE: brands may overlap):

<document>
	<brands>
		<brand>Brand F</brand>
		<brand>Brand E</brand>
	</brands>
</document>
<document>
	<brands>
		<brand>Brand B</brand>
		<brand>Brand A</brand>
	</brands>
</document>
<document>
	<brands>
		<brand>Brand C</brand>
		<brand>Brand D</brand>
	</brands>
</document>
<document>
	<brands>
		<brand>Brand C</brand>
		<brand>Brand A</brand>
	</brands>
</document>


Into this:

<document>
	<brands>
		<brand>Brand A</brand>
		<brand>Brand B</brand>
	</brands>
</document>
<document>
	<brands>
		<brand>Brand A</brand>
		<brand>Brand C</brand>
	</brands>
</document>
<document>
	<brands>
		<brand>Brand C</brand>
		<brand>Brand D</brand>
	</brands>
</document>
<document>
	<brands>
		<brand>Brand E</brand>
		<brand>Brand F</brand>
	</brands>
</document>


Any ideas would be greatly appreciated.
