Thank you very much for your explanation, Michael. Now I understand
better why things have to be this way.
The solution you suggested works perfectly for me. I am just a bit
disappointed that XSLT 2 doesn't provide with me a more elegant
construct that would make life even easier for me (like XSLT 2 already
did in a lot of cases). :-)

and what about that ?
<xsl:variable name="concat">
<xsl:sequence>
<xsl:value-of select="$a"/>
<xsl:value-of select="$b"/>
<xsl:value-of select="$c"/>
</xsl:sequence>
</xsl:variable>
<xsl:value-of separator="|" select="$concat[string-length(.) gt 0]"/>
Unfortunately, this won't work, as xsl:sequence only allows to use the
select attribute here, not its element content. However, adapting it a
little I get
<xsl:variable name="concat" select="($a, $b, $c)"/>
<xsl:value-of separator="|" select="$concat[string-length(.) gt 0]"/>
which seems to work (but I am not sure). Anyway, I prefer Michael's
solution.
