Right, but make sure when you're using the sort instruction that your context node is the corrent one for the sort select expressions. If you have 

  <xsl:for-each select="Subject">
    <xsl:sort select="Subject/@id" order="ascending" /> 
    <xsl:sort select="Subject/@id2" order="ascending" />
    <xsl:sort select="Subject/@id3" order="ascending" />
    <xsl:copy-of select="." />    
  </xsl:for-each>

that will not work, because the Subject doesn't have a Subject child. Instead use

<xsl:template match="f">
  <xsl:for-each select="Subject">
    <xsl:sort select="@id" order="ascending" /> 
    <xsl:sort select="@id2" order="ascending" />
    <xsl:sort select="@id3" order="ascending" />
    <xsl:copy-of select="." />    
  </xsl:for-each>
</xsl:template>
