Sorry, I didn't read the bottom.
You can only include one <xsl:when> as a child of <xsl:choose>. (There
is no concept of a case switch or elsif in XSLT.)
test="//eraname" returns true if there is an element <eraname> anywhere
in the document. To search only the children of the current node, take
out the '//' part.
To do what you want try this (anyone knows of a more elegant method,
please chime in):
<fo:block font-family="Helvetica" font-size="18pt"
text-align="end">
<xsl:choose>
<xsl:when test="eraname or conflictname">
<xsl:choose>
<xsl:when test="eraname">
<xsl:value-of select="eraname"/>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="conflictname"/>
</xsl:otherwise>
</xsl:choose>
</xsl:when>
<xsl:otherwise>
<xsl:text>History of the World</xsl:text>
</xsl:otherwise>
</xsl:choose>
</fo:block>
