It actually does something akin to

<xsl:array>
  <xsl:apply-templates select="array:parcels(.)" mode="#current"/>
</xsl:array>

or

<xsl:map>
  <xsl:apply-templates select="map:entries()" mode="#current"/>
</xsl:map>

There's a lot of detail to be fleshed out in turning the sketch given in the
paper into a full specification. But thanks for the comment,

Probably, but it would be pretty convoluted. These constructs take the
solutions to my XML Prague 2016 use cases from 100-200 lines of XSLT 3.0 code
down to 10-20 lines.
