..but here you aren't doing anything with the parameter 'parm', the
exists() test would applied to the root and not to <myelement>.

The whole thing could be rewritten as:

<xsl:template match="/">
  Age exists = <xsl:value-of select="boolean(//myelement[@name =
'karl'])"/>
</xsl:template>

If you really wanted it as a named template then you would need:

<xsl:template name="subtemp">
    <xsl:param name="parm"/>
    <xsl:for-each select="$parm">
        <xsl:value-of select="boolean(@age)"/>
    </xsl:for-each>
</xsl:template>
