[xep-support] xsl:for-each within xsl:variable

[Geoff Levner]

Actually it is neither FOP nor XEP that transforms your document, but 
whatever XSLT processor is being used.  I believe XEP uses Saxon by 
default, but you can set it up to use Xalan or whatever processor you 
want.  I don't know about FOP.

That said, I don't know why your code doesn't work, but a simpler 
solution might be to have two different templates: one for the first 
keyword, which would prefix the keyword by "Keyword(s):", and one for 
the others, which would prefix the keyword with a comma.  Something 
like this:

<xsl:template match="keyword[1]">
	<xsl:call-template name="display1">
		<xsl:with-param name="label" select="'Keyword(s):'" />
		<xsl:with-param name="content" select="..." />
	</xsl:call-template>
</xsl:template>

<xsl:template match="keyword">
	<xsl:call-template name="display1">
		<xsl:with-param name="label" select="','" />
		<xsl:with-param name="content" select="..." />
	</xsl:call-template>
</xsl:template>

I'm just typing off the top of my head, so I could be wrong about the 
exact syntax...
