RE: how to convert from list to grid ?

In 2.0, with <list> as the context node, it's something like this:

<xsl:variable name="list" select="."/>
<table>
<xsl:for-each select="1 to max(item/@x)">
  <xsl:variable name="x" select="."/>
  <tr>
  <xsl:for-each select="1 to max(item/@y)">
    <xsl:variable name="y" select="."/>
    <td>
       <xsl:value-of select="count($list/item[@x=$x and @y=$y])"/>
    </td>
  </xsl:for-each>
  </tr>
</xsl:for-each>
</table>

In 1.0, you can replace the for-each loops with a recursion, or with
something like

<xsl:for-each select="//node()[position() &lt;= $max-x]">
