something like :
<xsl:template match="plants">
  <xsl:for-each select="plant" order-by="plant[@color]"> 
   <xsl:variable name="currentColor"><xsl:value-of
     <xsl:attribute name ="color">
      <xsl:value-of select="@color"/>
     <xsl:value-of select="."/>
is supposed to read in something that looks like :
    <plant color="red">Rose1</plant>
    <plant color="blue">Rose2</plant>
    <plant color="red">Rose3</plant>
    <plant color="green">Rose4</plant>
and output a list of plants omitting the ones of which the
color occurred before.
