I wish it were a solution :-(. Rx:pinpoint is not a solution
to anything by itself, but rather a basic building block for
techniques that use formatter output postprocessing. It lets
you assign user-defined data to specific positions on the page;
these data can be used as pivots to add extra marks to the
page, intercepting its intermediate XML form between
the formatter core and the output generator.

Surely it is implemented; but it does not solve any problem
by itself. You just get a low-level method to build your own
solution; it will inevitably become very formatter-specific
(yet you are somehow compensated by nearly absolute freedom
to reorder page elements as you like :-)). We mention
rx:pinpoint in the documentation for the sake of completeness;
but we don't recommend its usage unless absolutely unavoidable.
