:{)} Only if you re-run the same processor you ran 10 years prior.

As I understand it, XSL-FO does not guarantee page fidelity between two 
conforming processors.  Each processor can generate a different area tree 
than the other as a result of interpreting the objects (because of 
hyphenation and justification, different initial values for half-leading, 
different choices for fonts when not specified by the stylesheet, etc.).

One can get asymptotically closer to page fidelity through rigourous 
specification of properties, but I don't think it can be guaranteed to 
specify enough to get identical area trees and renderings between two 
conforming implementations.
