Just to add a historical note to this. It is 
correct that the choice is with the first 
reviser. However, the "page precedence" has 
actually – as a last criterion - been part of 
Recommendation 24A in the first three editions of 
the Zoological Code (1961, 1964, 1985), and 
became omitted only in the last edition (1999).
