I think you solved it yourself when you used @outputclass='pagebreak'.

You indicated in off-list email that you are using XSLT 1.0, so
xsl:for-each-group isn't available to you.  What XSLT processor are you
using?  Does it implement exslt:node-set() [1]?  set:difference() [2]?

Actually, you may be able to do something like the following:

<xsl:for-each select="concept[title/@outputclass='pagebreak']">
  <xsl:variable name="position" select="position()" />

  <fo:page-sequence ...>
    ...
    <xsl:apply-templates
      select=". |
preceding-sibling::*[count(preceding-sibling::concept[title/@outputclass='pagebreak']
= $position - 1" />
  </fo:page-sequence>
</xsl:for-each>
