I think, as you need to materialize each document to process it for
references, I would write a function to collect all referenced documents
i.e. replace the code

 B B B  <xsl:variable name="topic-uri-collection1"

 B B B  <xsl:variable name="topic-docs" select="$topic-uri-collection1 !

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

from my previous suggestions with something along the lines of (assuming
of course you would declare namespace for the prefix "mf"B  somewhere)

<xsl:function name="mf:collect-docs" as="document-node()*">

 B  <xsl:param name="input-doc" as="document-node()"/>

 B  <xsl:variable name="topic-uri-collection"

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

 B  <xsl:sequence select="$topic-docs, $topic-docs ! mf:collect-docs(.)"/>



 B B B  <xsl:variable name="referenced-topic-docs"

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

I have no idea whether the DITA references could have cyclic references,
in that case that code above would cause an infinite recursion, I am
afraid. Therefore, be a bit careful before trying, I hope you know DITA
and your sample DITA documents better than I to judge whether the above
suffices and doesn't cause infinite recursion. If you know there can be
cycles of references, let us know, then we need some union to eliminate
duplicates and make sure the recursion only occurs on any newly found
