I was making it explicit for pedagogical reasons. XSLT 2.0's <xsl:value-of> will still act as it does in XSLT 1.0; it's only if you add a separator attribute that it creates a text node in which all the string values of the items in the sequence are included, separated by the string specified in the sequence attribute, e.g.: <xsl:value-of select="(1, 2, 3)" /> => "1" <xsl:value-of select="(1, 2, 3)" separator=" " /> => "1 2 3" <xsl:value-of select="(1, 2, 3)" separator"" /> => "123" Cheers, Jeni --- Jeni Tennison http://www.jenitennison.com/ XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
