Then here's the running-total part:

This xslt transformation:

<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns:f="http://fxsl.sf.net/";
 exclude-result-prefixes="f"
>
 <xsl:import href="../f/func-scanl.xsl"/>
 <xsl:import href="../f/func-Operators.xsl"/>

 <xsl:output omit-xml-declaration="yes" indent="yes"/>

 <xsl:template match="/">
    <xsl:for-each select="f:scanl1(f:add(), /*/*/@capacity)">
     <xsl:value-of select="concat(., ', ')"/>
    </xsl:for-each>
 </xsl:template>
</xsl:stylesheet>

when applied against the provided source xml document:

<xml>
<factory x="A" capacity = "3" />
<factory x="B" capacity= "5" />
 <factory x="C" capacity = "3" />
 <factory x="D" capacity = "2" />
 <factory x="E" capacity = "2" />
 ...etc...
</xml>

produces the wanted result (the list of running totals):

3, 8, 11, 13, 15,
