variable scope is just the eleemnt that contains the binding so never
outside a template. You don't need the reference in a separate template,
just put it in the first one. Actually you have two templates with teh
same match, which is an error, but in that case the error is recoverabe
(by just using teh last template defined) so as is the template that
defines the variable isn't only in a different scope it will never be
executed.


<xsl:stylesheet version="1.0"
          xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
          xmlns:exslt="http://exslt.org/common">
	<xsl:output indent="yes"/>
	<xsl:template match="/">
		<xsl:variable name="temp">
			<components>
				<xsl:copy-of
select="document(document('filenames_file.xml')/files/file)/components/component"/>
			</components>
		</xsl:variable>

		<components>
			<xsl:for-each select="exslt:node-set($temp)/components/component">
				<xsl:sort select="@name"/>
				        <name>
						<xsl:value-of select="@name"/>
					</name>
                                        ..
			</xsl:for-each>
		</components>
	</xsl:template>

</xsl:styleseet>

will merge and sort the components. Replacing the xsl:sort by a grouping
idiom will finish the job, something like (untested>

<xsl:stylesheet version="1.0"
          xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
          xmlns:exslt="http://exslt.org/common">
	<xsl:output indent="yes"/>
	<xsl:template match="/">
		<xsl:variable name="temp">
			<components>
				<xsl:copy-of
select="document(document('filenames_file.xml')/files/file)/components/component"/>
			</components>
		</xsl:variable>

		<components>
			<xsl:for-each select="exslt:node-set($temp)/components/component[generate-id()=generate-id(key('c',@name)]">
				<xsl:sort select="@name"/>
<xsl:copy>
<xsl:copy-of select="@*|key('c'@name)/*"/>
</xsl:copy>
			</xsl:for-each>
		</components>
	</xsl:template>

<xsl:key name="c" match="component" use="@name"/>
</xsl:styleseet>
