In the 6th paragraph is a sentence that seems to be missing something:
These elements make it possible to accommodate multiple images of each page, as well as to record the position and relative size of elements identified any kind of written surface and to link such elements with digital facsimile images of them.
My best guess is that "on" should come just before "any," but I'm not dead sure.
Rock on.
I agree. I've set this to green and assigned it to myself, and I'll make the change if no-one objects in the next day or two.
Fixed in rev 12854.
