I'm sure I'm missing something simple here, but I can't figure out how to tell whether or not the optional parameter is provided for the template below: <xsl:template name="assignment"> <xsl:param name="name" required="yes"/> <xsl:param name="value" required="no"/> <xsl:variable name="value0"><xsl:value-of select="$value"/></xsl:variable> <xsl:value-of select="$name"/> <xsl:if test="string-length($value0) &gt; 0"> <xsl:text> := </xsl:text> <xsl:value-of select="$value0"/> </xsl:if> <xsl:text>;</xsl:text> </xsl:template> The value could be the empty sequence, a single string (which could be empty, in which case I don't want to output the ":=" operator), or it could be a sequence of strings that together represent some kind of compound expression. using value-of to serialize the parameter is the only way I have come up with to effectively test whether the parameter is present, but it seems rather roundabout. Any suggestions would be welcome. Regards, Joe.
