Hi Ken,
I was not careful in the way I described this problem. Each group consists 
of a single title with one or more citations. What I must have said is that 
I wanted to set the Title in each group to "keep". What I *should* have said 
was, I want to set the only the first group to "keep". For the input data at 
the end of this email, that would be the title "Further observations". All 
the rest would not be marked "keep".

Clearly, I do not want (from listing 1):
                    <xsl:if test="position()=1">
                        <xsl:attribute 
name="keep-with-previous">always</xsl:attribute>
                    </xsl:if>
However, I do not know XPath well. How do I select only the first group for 
marking and let the other groups pass without marking them?

All help appreciated.
Mark

Listing 1:

        <xsl:for-each-group select="../Article" group-by="Title">
            <xsl:sort select="Title"/>
            <xsl:sort select="Year"/>
            <xsl:sort select="IssueNumber" data-type="number"/>
            <xsl:sort select="Page"/>
            <xsl:for-each select="current-group()">
                <fo:table-row>
                    <!-- Put the first group in a keeping row-->
                    <xsl:if test="position()=1">
                        <xsl:attribute 
name="keep-with-previous">always</xsl:attribute>
                    </xsl:if>
