Variables

Dear all,

Could someone explain me the following example of the W3C specification

<xsl:variable name="n">2</xsl:variable>
...
<xsl:value-of select="item[$n]"/>

This will output the value of the first item element, because the variable n
will be bound to a result tree fragment, not a number.
(See chapter 11.2)

What is the reason for outputing the value of only the first item element ?

Best regards
