I don’t understand. If there is no computerized way to represent the script, all you can do would be to include photographs in your pdf. The point of computerization is not simply storage and retrieval (and retrieval is hard if you can’t represent the script) but automated processing, which is meaningless if you can’t represent any semantics).

Separately, PDF felt like a step backwards on the day it was announced and sadly nothing since then has changed that.
