    <xsl:template match="@* | node()">

    <xsl:template match="RENAME">
        <DONE>
            <xsl:apply-templates select="@* | node()"/>
        </DONE>
    </xsl:template>
    <xsl:template match="@RENAME">
        <xsl:attribute name="DONE">

<variables>
    <var>
        <DONE> a </DONE>
    </var>
    <var DONE="b"></var>
    <var>
        <DO_NOT_TOUCH> c </DO_NOT_TOUCH>
    </var>
    <var DO_NOT_TOUCH="d"></var>
</variables>

    <xsl:element name="{$Foo}"> a </xsl:element>
  </var>
  <var DONE='b'/>
  <var>
    <DO_NOT_TOUCH> c </DO_NOT_TOUCH>
  </var>
  <var DO_NOT_TOUCH='d'/>
</variables>
