But surely it's not that hard to write a recursive template or function
that finds the previous page break and adds one to it where needed?
Roughly,

If this is the first page number then (@n, 1)[1]
If @n is supplied then @n
Otherwise 1 + pagenumber( (preceding::pagebreak)[1] )

If performance is an issue you can ask saxon to memoize (remember) the
function results.
