It looks like you have the first 8 values, and just want help with the
total.  I did it with this line:

    <xsl:value-of select="sum(assetWeights[position() &gt;
        8]/@weight)"/>

Obviously, in the context of the <snip/> root.  You'd have to rewrite it
slightly to work in your for-each block, but I think you should ditch
the for-each and work directly from templates called from the parent so
as to (easily) avoid the repetition across every child with position
greater than 8.

Here's my full test stylesheet:

    <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; 
                    version="1.0">
        <xsl:output method="text"/>

        <xsl:template match="/snip">
            <xsl:value-of select="sum(assetWeights[position() 
                &gt; 8]/@weight)"/>
        </xsl:template>
    </xsl:stylesheet>

Which returns 0.727.  Also obviously, I'm temporarily ignoring the
sorting requirement, but your code looks like it already takes care of
that.

Take care,
