How to get a case insensetive grouping ??

Hi,
I'm using the Muenchian Method to group elements of a xml file. Currently my
xsl produces separate groups for identical words with different spelling
(upper-/lower-case). Is there an easy way to create an 'overall' group for
such elements (e.g. "NAME" and "name")? I've tried translate() but that
seems not to work.

Thanks,
-Michael


XSL sample ....

<xsl:key name="elementToGroup_" match="level2/level3"
use="translate(elementToGroup,'abcdef...','ABCDEF...')" />
<xsl:output method="html"/>

<xsl:template match="level1">
	<xsl:apply-templates select="level2/level3[generate-id(.) =
generate-id(key(elementToGroup_', elementToGroup)[1])]" />

.....

XML sample ....
<level1>
	<level2>
		<level3>
			<elementToGroup>NAME</elementToGroup>
			<element>xxx</element>
		</level3>
	</level2>
	<level2>
		<level3>
			<elementToGroup>name</elementToGroup>
			<element>yy</element>
		</level3>
	</level2>
</level1>
