While I am all for using FP, this is the most unreadable of all
proposed solutions.

Eliot specifically asked for XSLT 2 solution.

The 10-lines non-recursive, based on practical limitations XSLT 2.0
solution, compared to the XSLT 3.0 solution using fold-left() (or
<xsl:iterate>)  is similar to the Indian space ship that reached Mars
for less than it cost to make "Gravity":
