Variables cannot be used in patterns in XSLT 1.0. (In XSLT 2.0 they can be 
used.)

Now you "select all and match only those elements that qualify" (and let the 
rest be handled by build-in templates). How about changing the approach to 
"select the qualifying elements only".

  <xsl:template match="/">
    <table cellspacing="0" cellpadding="2" class="{$css}">
      <tr>
        <td class="ui_tree_bar">
          <a href="{$url}&amp;action=add">add</a>
        </td>
      </tr>
      <xsl:apply-templates select="tree/descendant::tree_node[(_at_)id = 
$id]/tree_node"/>
    </table>
  </xsl:template>
  <xsl:template match="tree_node">
    <tr>
      <td>
        <table width="100%">
          <tr>
            <td align="right" width="{count(ancestor-or-self::*) * 10}">
              <a href="{$url}&amp;node={(_at_)id}">+</a>
            </td>
            <td>
              <xsl:value-of select="@value"/>
            </td>
            <td width="25%">
              <a href="{$url}&amp;action=edit&amp;node={(_at_)id}">edit</a>
              <a href="{$url}&amp;action=delete&amp;node={(_at_)id}">delete</a>
            </td>
          </tr>
        </table>
      </td>
    </tr>
  </xsl:template>
