This is the @LarsH in other words:

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
    <xsl:strip-space elements="*"/>
    <xsl:output indent="yes"/>

    <xsl:template match="PARM">
        <facet-groups type="array">
            <xsl:apply-templates select="PMT"/>
        </facet-groups>
    </xsl:template>

    <xsl:template match="PMT">
        <facet-group>
            <name><xsl:value-of select="@NM"/></name>
            <facets type="array">
                <xsl:apply-templates select="PV"/>
            </facets>
        </facet-group>
    </xsl:template>

    <xsl:template match="PV">
        <facet>
            <name><xsl:value-of select="@V"/></name>
            <count><xsl:value-of select="@C"/></count>
        </facet>
    </xsl:template>

</xsl:stylesheet>
