Have you tried wrapping the affiliation bit in a for-each? Something like:

  <xsl:for-each select=".//presentation">
    <xsl:for-each select=".//person">
      <xsl:value-of select="normalize-space(.)"/><xsl:text>&#09;</xsl:text>
      <xsl:for-each select="affiliation"/>
          <xsl:value-of select="."/><xsl:text>|</xsl:text>
     </xsl:for-each>
      <xsl:text>&#09;</xsl:text>
      <xsl:value-of select="normalize-space(../
paper)"/><xsl:text>&#10;</xsl:text>
    </xsl:for-each>
  </xsl:for-each>
