Sample Code for multiple fo:page-sequence

I am generating a big PDF report comprising of hundreds of pages, and I get
outOfMemory messages. I am using no images,  I have already adjusted the
-Xms and -Xmx vals to 256M/512M on my 512M NTmachine. I do not have any
"Page x of y" type of references. Based on apache's recommendation,  one
big reason for continuing to get the outOfMemory is because of I have all
of my data based in a single table which in turn is inside a single
sequence.I can have multiple sequences in one of 2 ways:
- call for a fresh page sequence after, say every 20 records (preferable,
since the data volume varies for each record).
- call for a page sequence per new page, wherein I specify that the number
of records per page is, say, 5
Can anyone point out how I can re-code my XSL.

An simplified example of my XML is:
<ROWSET>
      <ROW>
            <SSN></SSN>
            <NAME></NAME>
            <ADDRESS></ADDRESS>
            <INFO>This text could run into 1 or more sentences depending on
the record</INFO>
      </ROW>
      <ROW>
      - - - - - - - - - - -
      </ROW>
      - - - - - - -
</ROWSET>

My XSL looks like this:
<fo:page-sequence master-reference="default-master">
  <fo:static-content flow-name="xsl-region-before">
    ---------
  </fo:static-content>

  <fo:static-content flow-name="xsl-region-after">
    ----------
  </fo:static-content>

  <fo:flow flow-name="xsl-region-body">
    <fo:table table-layout="fixed">
      <fo:table-column column-width="20mm" background-color="white"/>
      <fo:table-column column-width="43mm" background-color="white"/>
      <fo:table-column column-width="20mm" background-color="white"/>
      <fo:table-column column-width="43mm" background-color="white"/>
      <fo:table-header>
        - - - - - - - - -
      </fo:table-header>
      <fo:table-body>
        <xsl:apply-templates select="document
('AllEmployees.xml')/ROWSET/ROW">
        </xsl:apply-templates>
      </fo:table-body>
    </fo:table>
  </fo:flow>
</fo:page-sequence>

<xsl:template match="ROW">
    <fo:table-row keep-with-next="always">
      <fo:table-cell>
        <fo:block><xsl:value-of select="SSN"/></fo:block>
      </fo:table-cell>
      <fo:table-cell>
        <fo:block><fo:block><xsl:value-of select="NAME"/></fo:block>
      </fo:table-cell>
      <fo:table-cell padding="1.0pt">
        <fo:block><xsl:value-of select="ADDRESS"/></fo:block>
      </fo:table-cell>
      <fo:table-cell padding="1.0pt">
        <fo:block><xsl:value-of select="INFO"/></fo:block>
      </fo:table-cell>
    </fo:table-row>
</template>
