variable match attribute

Hello,

sorry for possible reposting but the archive server seems to be down....

I want to to something like that:

.
.
<xsl:variable name="start" select="document('start.xml')/START"/>
<xsl:variable name="pattern">
	<xsl:for-each select="$start/*">
		<xsl:value-of select="name()"/>
		<xsl:if test="not(position()=last())">
			<xsl:text>|</xsl:text>
		</xsl:if>
	</xsl:for-each>
</xsl:variable>
.
.

<xsl:template match="$pattern">
	<!-- do something -->
</xsl:template>

I know, the match attribute is a pattern, where I can't use variables
but how can I solve the problem:
'read element names from a document B and use them as template pattern
in document a'



Mit freundlichen Grüßen
Michael Schäfer
