Unless you mean doing an annotation highlight  and not text selection highlighting?

Sorry, yes, I meant the highlighter annotation tool.

That's a requirement of the PDF specification, Annotations are attached to a page, so you can't create multipage annotations.

Perhaps the user-facing thing could create different annotations for different pages, so that it looks like it did go across pages?

That's just asking for trouble. Imagine we do that, then you add a comment in that fake multipage annotation (the thing that opens when you double click). 

We could  force the same comment to both of the annotations, but then you send that file to someone else, they open it in Adobe Reader, they edit the comment of one of the annotations, send it back to you saying they have done that, and you see no change (because you're clicking on the other annotation, in your mind both annotations are the same annotation when they really are not).

So no, just create multiple annotations.

That makes sense, thank you for the explanation :)
