  <!-- Section: 11.2 Values of Variables and Parameters  -->
  <!-- Purpose: Test for handling of RTF used as positional index by setting
        variable as the content of the xsl:variable element. Reference as [$n].
        This is the case that will NOT obtain what a naive person expects. -->
  <!-- Author: Paul Dick -->
  <!-- Note: When a variable is used to select nodes by position, 
             be careful not to do: 
             <xsl:variable name="n">2</xsl:variable>
                ...
             <xsl:value-of select="item[$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. Instead, do either 

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

<xsl:template match="doc">
  <xsl:variable name="n">2</xsl:variable>
  <out>
    <xsl:value-of select="item[$n]"/>
  </out>
</xsl:template>
