Gerrit,
good solutions.
While the simpler with Root1.xml as input is to prefer it
is also XSLT 1.0.
I modified your other solution in order to emulate 3-argument
XPath2 key function in XSLT 1.0:
<xsl:template match="/">
- <xsl:for-each select="key(
- 'idlist',
- key('idlist', $data/root1/item/@id)/@id,
- $data
- )
- ">
- <xsl:value-of select="@value"/>
- <br/>
+ <xsl:variable name="ids"
+ select="key('idlist', $data/root1/item/@id)/@id"/>
+ <xsl:for-each select="$data">
+ <xsl:for-each select="key(
+ 'idlist',
+ $ids
+ )
+ ">
+ <xsl:value-of select="@value"/>
+ <br/>
+ </xsl:for-each>
</xsl:for-each>
</xsl:template>
$ xsltproc 2.xsl Root1.xml
A<br/>C<br/>E<br/>F<br/>H<br/>I<br/>J<br/>
$
$ saxon 1.xsl Root2.xml ; echo
A<br/>C<br/>E<br/>F<br/>H<br/>I<br/>J<br/>
$
$ xsltproc 1a.xsl Root2.xml
A<br/>C<br/>E<br/>F<br/>H<br/>I<br/>J<br/>
$

You key function returns the elements of Root2.xml whose id matches
those of the Root1 items.
But ultimately you want to lookup the value attributes of the
corresponding Root1 elements.
If you really want to process root2.xml as primary source, you may try
this (XPath2's 3-argument key function involved):
In fact, it's the XSLT2 and not an XPath2 key function:
