Hi,
Please see the below stylesheet. This was done by me independently
by me. Of course after taking some help from previous postings.
<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns:foo="http://whatever";>
<xsl:output indent="yes"/>
<xsl:template match="root">
<root>
<xsl:variable name="origdoc" select="/"/>
<xsl:for-each-group select="*"
group-starting-with="*[(_at_)color=('dark-red')] ">
<xsl:choose>
<xsl:when test="self::*[(_at_)color='dark-red']">
<xsl:for-each-group select="current-group()"
group-ending-with="*[(_at_)color='light-red']">
<xsl:choose>
<xsl:when
test="current-group()[last()][self::*[(_at_)color='light-red']]">
<red>
<xsl:copy-of
select="current-group()"/>
</red>
</xsl:when>
<xsl:otherwise>
<xsl:copy-of select="."/>
</xsl:otherwise>
</xsl:choose>
</xsl:for-each-group>
</xsl:when>
<xsl:otherwise>
<xsl:copy-of select="."/>
</xsl:otherwise>
</xsl:choose>
</xsl:for-each-group>
</root>
</xsl:template>
</xsl:stylesheet>

That is of course if I've scaled up the input correctly, no comment
from the OP so far.
Yes, this is how the input would scale. I'm sorry for not replying
earlier to the solutions given so far (Andrew, David) - I must admit
that I am still digesting the code given to extract and understand the
underlying idea(s).
For your (Andrew's) solution to example #1, am I right that the
underlying idea could be paraphrased as:
"Group by start, then tail-trim the resulting groups to end (using a
nested grouping from end)"?
Yes - I would call it "intersecting" rather than "trimming", its
providing the end marker for the group. The elements that aren't in
the intersect are copied to the result (in the xsl:otherwise blocks)
so trimming might give the wrong impression.
