I, for one, am not sure what you are after.  What comes before and after
this <concept>?  Is it nested within several levels of elements or is it a
child of the document element?

If the <concept> is a child of the document element, then it might be as
simple as using xsl:for-each-group [1] with 'group-ending-with', e.g.:

<xsl:for-each-group
    select="*"
    group-ending-with="concept[title/@xtrf = 'GUID-1234']">
  <fo:page-sequence ...>
    ...
    <xsl:apply-templates select="current-group()" />
  </fo:page-sequence>
</xsl:for-each>

If you need to do this for multiple specific <context>, you can use a
sequence of @xtrf values in the predicate instead, e.g.:

   title/@xtrf = ('GUID-1234', 'GUID-5678')

It's more commonly referred to as a 'fragment', BTW: 'content model' is a
term from DTDs for the definition of what's allowed in a particular
element.

Presumably the 'last()' is for this particular <concept> only?
