how to sort after applying generate-id()?

Hello - 
 I'm having trouble sorting the item grouped by generate-id()...


I have xml that looks like

<REPORT>
 <ENTITY>
         <FUND_CURRENCY_GROUP CURRENCY="GBP">
                 <FUND_CODE_GROUP TA_FUND_CODE="G631">
                         <FUND_ROW>
                                  <TRADE_TYPE>PUR</TRADE_TYPE> 
                          </FUND_ROW>
                  </FUND_CODE_GROUP>
          </FUND_CURRENCY_GROUP>
          <FUND_CURRENCY_GROUP CURRENCY="USD">
                 <FUND_CODE_GROUP TA_FUND_CODE="U631">
                         <FUND_ROW>
                                  <TRADE_TYPE>PUR</TRADE_TYPE> 
                          </FUND_ROW>
                  </FUND_CODE_GROUP>
          </FUND_CURRENCY_GROUP>
 </ENTITY>
  
  and many more ENTITY like this
  </REPORT>


XSL looks like follwing:

                <xsl:variable name="currencies"
select="//FUND_CURRENCY_GROUP"/>

                        <xsl:if test="generate-id(.)=
                            generate-id( $currencies[ @CURRENCY =
                                        current()/@CURRENCY ] )">


                        <tr>
                            <td colspan="4"><b>Grand Total Purchases
(<xsl:value-of select="@CURRENCY"/>):</b></td>
                            <td align="right" width="14%">&#160;</td>
                            <td align="right" width="14%">&#160;</td>
                         </tr>

                        <tr>
                            <td colspan="4"><b>Grand Total Redemptions
(<xsl:value-of select="@CURRENCY"/>):</b></td>
                            <td align="right" width="14%">&#160;</td>
                            <td align="right" width="14%">&#160;</td>
                        </tr>

                        <tr>
                            <td colspan="4"><b>Grand Total Net Change
(<xsl:value-of select="@CURRENCY"/>):</b></td>
                            <td align="right" width="14%">&#160;</td>
                            <td align="right" width="14%">&#160;</td>
                            <!-- I would do something like this, if it works
<td align="right" width="14%"><b><u><xsl:value-of select="format-number(sum(
$currencies[(_at_)CURRENCY=current()/@CURRENCY]/FUND_CODE_GROUP/@TOTAL_FUND_VALUE
_NET ), '#,###,###,##0.00')"/></u></b></td> -->
                        </tr>
                            </xsl:if>
                        </xsl:for-each>


        This would return me cross-entities grouped by currency

        Grand Total Purchases (USD)
        Grand Total Purchases (GBP)
        Grand Total Purchases (EUR)

        This is good, but is there anyway to combine sorting with this
generate-id() so that it appears alphabetically?

        Grand Total Purchases (EUR)
        Grand Total Purchases (GBP)
        Grand Total Purchases (USD)

 Thanks
