This fixation with page numbers is getting too anal. No matter what is done, everyone won't be satisfied. It really a dead horse.
Being fat, dumb, and happy with Marvin -- warts and all -- as a reader for standard books seems to be raison d'etre enough for me.
Had no idea about ADE so I had to go look.
The site seems a great one for epub nuts and bolts.
The first paragraph about ADE says:
Page numbering is automatically generated and inserted by ADE. There is a way we, as content developers, can either manually establish page number or disable it altogether, however as of Dec 2011 it requires the use of a proprietary Adobe extension to the .opf that will cause VALIDATION FAILURE. Continue at your own risk.
Looks like Schwartz has friends in the forget page numbering lands.
