plan a is to convert the whole lot into a string, either using a special

markup back, again either with a special mode, or just use saxon:parse()

plan b is to first convert every || to an element say <split/> just
using an identity transfom plus a teplate matching "text()". Then once
it is all nodes, you can run a xsl;group-by with group-starting with
split, to split them up.

How hard the problem is depends to a great extent on whether the delimiter (markup or pseudo-markup) can be buried deep in the node, or whether it can split only children.

If the former, it can be necessary to flatten and then induce a new hierarchy. (This is actually a special case of an overlap problem.) But it appears that James only has to do the latter.
