Depending what exactly you mean by "labels like skos:altLabel or
skos:prefLabel", use the modified identity stylesheet pattern:

  <xsl:template match="skos:altLabel|skos:prefLabel">
    <xsl:copy>
      <xsl:attribute name="xml:lang">en</xsl:attribute>
      <xsl:copy-of select="@*"/>
      <xsl:apply-templates select="@*|node()"/>
    </xsl:copy>
  </xsl:template>

  <xsl:template match="*">
    <xsl:copy>
      <xsl:copy-of select="@*"/>
      <xsl:apply-templates select="@*|node()"/>
    </xsl:copy>
  </xsl:template>

This relies on the fact that if you add the same attribute to an element
twice, the last one wins.
