<xsl:comment>
  <xsl:text>count: </xsl:text>
  <xsl:value-of select="count(//lc:container[lc:item]/@select)"/>
</xsl:comment>
<xsl:comment>
  <xsl:text>list of select attributes: </xsl:text>
  <xsl:for-each select="//lc:container[lc:item]/@select">
    <xsl:value-of select="."/>
    <xsl:text> </xsl:text>
  </xsl:for-each>
</xsl:comment>

I'm not having much success using the sum() function over a node set.

The following two expressions

<xsl:comment>
  <xsl:text>sum: </xsl:text>
  <xsl:value-of select="sum(//lc:container[lc:item]/@select)"/>
</xsl:comment>
<xsl:comment>
  <xsl:text>list of select attributes: </xsl:text>
  <xsl:for-each select="//lc:container[lc:item]">
    <xsl:value-of select="@select"/>
    <xsl:text> </xsl:text>
  </xsl:for-each>
</xsl:comment>

result in the following output:

    <!--sum: 0-->
    <!--list of select attributes: 2 3 1 -->

I'm not clear why the result of sum() is 0. Are there any other prerequisites that I'm missing?

Thanks again.
