      I have two book author names marked up in <authorgroup>:

    
<authorgroup role="leadauthor">

                                           
        <author>

                                           
                    <personname><honorific>Mr</honorific><firstname>John</firstname><surname>Smith</surname></personname>

                                                       
        <contrib>Lead author
        contribution</contrib>

                                                       
        <affiliation>

                                                                   
        <shortaffil>Short
        affil.</shortaffil>

                                                                   
        <jobtitle>Job title</jobtitle>

                                                                   
        <orgname>Organisational
        affiliation</orgname>

                                                                   
        <orgdiv>Org div</orgdiv>

                                                                   
        <address>Org address</address>

                                                       
        </affiliation>

                                           
        </author>

                                           
        <author>

                                                       
        <personname>Name of
        second lead author</personname>

                                           
        </author>

                                </authorgroup>

    
 

    
My first issue is trying to generate both
      <author> names
      in separate meta elements in HTML5 using 1.78.1-ns. This is all I
      get:

    
<meta
        name="dcterms:creator" content="Smith, John" />

    
I have a customization that generates only the
      first author’s
      names (firstname and surname) – I don’t get the second author, nor
      do I get any
      content inside only <personname> (so far I need both
      <firstname>
      and <surname> to generate content):

    
<xsl:template name="user.head.content">

            <xsl:param name="node" select="."/>

            <xsl:variable name="info" select="(d:info)[1]"/>

    
…

    
<xsl:if test="$info and
        $info//d:author[ancestor::d:authorgroup[@role='leadauthor']]">      

              <meta name="dcterms:creator">

                  <xsl:attribute name="content">

                    <!--<xsl:call-template
        name="person.name.last-first">

                 
        <xsl:with-param name="node" select="."/>

               
        </xsl:call-template>-->

                      

                    <xsl:choose>

                      <xsl:when test="descendant::d:surname">

                        <xsl:value-of select="normalize-space(string($info/d:authorgroup[@role='leadauthor']/d:author/d:personname/d:surname))"/>

                        <xsl:text>, </xsl:text>

                        <xsl:value-of select="normalize-space(string($info/d:authorgroup[@role='leadauthor']/d:author/d:personname/d:firstname))"/>

                      </xsl:when>

                      <xsl:otherwise>

                        <xsl:value-of select="normalize-space(string($info/d:authorgroup[@role='leadauthor']/d:author/d:personname))"/>    

                      </xsl:otherwise>

                    </xsl:choose>

                  </xsl:attribute>  

              </meta>

              

            </xsl:if>

    
…

    
</xsl:template>

    
 

    
I tried using xsl:for-each around the
      <meta> coding,
      and then again inside <meta>, but that generates the first
      author’s name
      multiple times in one <meta> element. I can’t see any clues
      from the EPUB
      metadata stylesheets either.

    
So: (1) How do I generate one meta element *for
      each author*,
      and (2) What coding works to generate content marked up in
      <personname>
      only (i.e. no child elements)?
