Here is an attempt to avoid the various modes and the accumulator by
trying to simply select the various URIs and then their documents and
finally the elements you seemed to want to collect with XPath:

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";

 B B B B xmlns:xs="http://www.w3.org/2001/XMLSchema";

 B B B B xmlns:math="http://www.w3.org/2005/xpath-functions/math";

 B B B B xmlns:map="http://www.w3.org/2005/xpath-functions/map";

exclude-result-prefixes="xs math map"

version="3.0" expand-text="yes">

<xsl:variable name="topic-uri-collection1"
select="//*/@href[matches(.,'(dita(map)?|xml)$','i')]/resolve-uri(.
,base-uri(.))[doc-available(.)]"/>

<xsl:variable name="topic-docs" select="$topic-uri-collection1 ! doc(.)"/>

<xsl:variable name="summary-data" select="$topic-docs ! (.//tool |
.//spare | .//supply)"/>

<xsl:output indent="yes"/>

<xsl:template match="/">
<map-data>

<summary>

<xsl:for-each-group select="$summary-data" group-by="normalize-space(.)">

<xsl:sort select="local-name(.)"/>

<xsl:sort select="normalize-space(.)"/>

<xsl:element name="{local-name(.)}"><xsl:attribute name="quantity"
select="sum(current-group()/@quantity)"/>{normalize-space(.)}</xsl:element>

</xsl:for-each-group>

</summary>

</map-data>
</xsl:template>

</xsl:stylesheet>


Perhaps that makes it easier for you to then use the global variable and
process the data with a mode. Note that the above with a simple XPath
selection will only work if you have that topic map referencing all
other documents, but not if referenced documents can as well reference
further documents; in the latter case you would need a recursive function.
