This is a standard pattern. An identity template:

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

supplemented by a template rule to change what you need to change

<xsl:template match="foo">
  <bar>
    <xsl:apply-templates/>
  </bar>
</xsl:template>
