Thanks for this, Florent! I guess more of what I was asking was along the lines of given two scenarios where, as far as a human is concerned, the output is the same, would it be preferable to use xsl:sequence or xsl:value-of? For example,
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0">
<xsl:variable name="elem" as="element()"> <elem>foo</elem> </xsl:variable>
<xsl:template match="/"> <xsl:sequence select="$elem/text()" /> </xsl:template>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0">
<xsl:variable name="elem" as="element()"> <elem>foo</elem> </xsl:variable>
<xsl:template match="/"> <xsl:value-of select="$elem/text()" /> </xsl:template>
will both produce 'foo' in the final serialized output. In this regard, is there a reason why one might use xsl:sequence over xsl:value-of or vice-versa?
