Re: [xsl] Two possible group-ending-with nodes

["Michael Kay michaelkay90@xxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

It ends the first inner group at the first element because it matches the
first condition, p[@class='CBNoteBody']; it ends the second inner group at the
second element because it matches the second condition
p[@class='CBBodyIndented'][@style='margin-left:96px;'], and it ends the third
inner group at the third element because everything after the last matching
element goes in a final group regardless.
