Sounds a little bizarre. What is the use case?Why can't you use the ordinary method: put an id on the FO you want to reference and use it in the link?
Because I want to reference exactly the previous page. I have no way of knowing this until after the XSLT stage.
There is no such a formatting object as page, instead pages are generated while formatting objects flow is not exhausted and that makes sense, because usually people want to reference some semantic objects like table, image or paragraph, but what would be a reason to reference just previous page?
