Select user-element inside <indexterm> in autoindex

["Mykone Saunders" <mykone@i3dvr.com>]

Anybody know how to get specific tag to output in the AutoIndex?

Example, I have the following user-defined element:

<indexterm zone="intro">
	<primary>
		<translation>
			<english>Introduction</english>
			<french>Introductiones</english>
		</translation>
	</primary>
</indexterm>

What XSL customization would I had to print only the translation/french
element as my index entry?

Your assistance would be greatly appreciated. Thanks in advance.
