The "group-adjacent" solution seemes obvious but I have to account for
various parent elements that all have different templates. Wouldn't
using the group-adj. solution mean that I have to edit each and every
template that can possibly contain <points>?

I did not notice the requirement of different parent templates so I was thinking in doing

  <xsl:template match="*[point/@type = 1]">
          <xsl:for-each-group select="*"
group-adjacent="boolean(self::point[@type = 1])">
                  <xsl:when test="current-grouping-key()">
                          <xsl:apply-templates select="current-group()"/>
                      <xsl:apply-templates select="current-group()"/>

It is certainly possible to put the grouping code into a function to use it in different templates, hard to tell whether that will work with the various parent elements having different templates without seeing how these templates look.
