RE: [xsl] Grouping Problems XSLT2.0

["Michael Kay" <mike@xxxxxxxxxxxx>]

It looks to me like

<xsl:for-each-group select="para"
group-starting-with="*[class='epigraphpara' or (class='subsection1para' and
inline)]">

(then having done hte grouping you need to inspect the first element of each
group to see what element to output)
