RE: [xsl] Merging lines of 3 words or less

["Michael Kay" <mike@xxxxxxxxxxxx>]

You can read this as a special case of the following:

<xsl:for-each-group select="line" group-starting-with="line[XXX]">
  do group-heading
  <xsl:for-each select="current-group()">
    process a line
  </xsl:for-each>
  do group-footing
</xsl:for-each-group>

Which means: process all the lines; before the first line and whenever you
encounter one that satisfies XXX, produce a group heading; at the end of a
group, produce a group footing. The value of current-group() is the set of
lines making up the group you are processing at the time.
