<xsl:variable name="foo1"/>
<xsl:variable name="bar1" select= "'world'"/>
<xsl:value-of select="($foo,$bar)[1]"/> <!--first-->
<xsl:value-of select="(string($foo1),$bar1)[1]"/><!--Second-->
First worked but second did not work
I was expecting "World" to be output to the result ..
Oh no, string($foo1) gives you an empty string, which is a valid first member
of the sequence, so that is what you get.
