This is a FAQ if (in XSLT1) you use xsl:variable with content then it always gennerates a result tree fragment which correspnds to a root node with a child a text node with the string value of the content. This acts like a node set with a single / node, in particular it's non empty so acts as true(). don't do this <xsl:variable name="false"> <xsl:call-template name="get-false"/> </xsl:variable> <xsl:template name="get-false"> <xsl:value-of select="false()"/> </xsl:template> do this <xsl:variable name="false" select="false()"/> the first version is equivalent to <xsl:variable name="false">false</xsl:variable> which corresponds to a document with thattext, so is non empty and has boolean value true().
