This approach is a little more table-driven:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:x="foo" exclude-result-prefixes="x">
<x:keynode>head1</x:keynode>
<x:keynode>head2</x:keynode>
<xsl:key name="parent" match="p"
use="generate-id(preceding-sibling::p[string(.) =
document('')//x:keynode/text()])" />
<xsl:variable name="head-types"
select="document('')//x:keynode/text()"/>
<xsl:template match="p[. = $head-types]">
<xsl:element name="{.}">
<xsl:apply-templates select="key('parent', generate-id())[not(. =
$head-types)]"
mode="inner"/>
</xsl:element>
</xsl:template>
<xsl:template match="p"/>
<xsl:template match="p" mode="inner">
<sub>
<xsl:copy-of select="."/>
</sub>
</xsl:template>
</xsl:stylesheet>
