This is a little odd. The default value for the parameter sortAmount,
if none is given, is a possibly sorted sequence  of highlight elements;
if a value is supplied, no sorting is done.

At the very least i'd suggest using
  <xsl:param name="sortAmount" as="element(highlight)*">
  . . .
  </xsl:param>

Don't try to reuse variables/parameters - if a parameter sometimes
means one  thing and sometimes means something else, use two different
parameters, and, if necessary, a third to say which meaning is
intended.
