Funny, I always thought the FLWOR was an XQuery only thing...

(Looks quite horrible to me, like someone couldn't decide between XQuery
and XSLT.. :-/)
Well, in 2.0 it isn't a full FLWOR expression ... no "let", no
"where" (though this can often be done with a predicate) and no
"order by". That is the difference between the XPath "for
expression" and XQuery "FLWOR expression".
But I have found it useful to say things like:
<xsl:value-of select="for $each in expr return expr2($each)"/>
or:
<xsl:apply-templates
select="for $this in expr1, $that in expr2 return expr3($this, $that)"/>
