OK: you need to wrap it like this:

> >  <xsl:sort>
      <xsl:value-of>
> >    <xsl:for-each select="@*">
> >      <xsl:sort select="name()"/>
> >      <xsl:value-of select='name(), "=""", ., """ "' separator=""/>
> >    </xsl:for-each>
      </xsl:value-of>
> >  </xsl:sort>
> >  <xsl:copy-of select="."/>
> > </xsl:for-each>
