This reads to me like

<xsl:if test="current-group()/*[@StyleName='DIVISION']">
  <xsl:for-each-group select="current-group() except "." 
 	group-starting-with="*[@StyleName='DIVISION']">
...
</xsl:if>

But I may have misunderstood the requirement. What do you want to happen
if there isn't a DIVISION item in the group?

Clearly the XSLT must be well-formed XML, so the closing tags have to be
properly nested, and they will then also be properly nested in the
result document. In fact, it's impossible to output a document in which
the tags aren't properly nested! So I don't think I understand the
question.
