In my response to Tony I used XT19990514 that supports XSL19990421:

In that posting you will see a working solution.

My understanding of generate-id() is that it must be used blindly:  values
are not persistent between executions of the stylesheet, but within any one
execution of the stylesheet the value for each node is persistent ... but
that is all.  I believe engines can assign any value they wish and that
their only lexical constraint is that they be parseable as name tokens
(*very* useful for indexes and TOCs), not that they be in any particular
order.
