You're right.
I could blame reading the the post too quickly but in truth I'm still a
beginner in version 2.0 :)

I think Joe got it wrong. It's not the otherwise branch that's the problem,
it's the when:
<xsl:when
>test="contains($xsrc,'/images/images/')">
><xsl:text>images/</xsl:text>
><xsl:value-of select="substring-after($xsrc,'/images/images/')" />
></xsl:when>
xsl:text creates a text node, xsl:value-of creates a second text node, and
you can't convert a sequence of two text nodes to a single string.
