Yes, I realised that. The value of doing it over elements specified by xpointers is that you can also have a checksum for the particular elements, so you can figure out which of those are different, break the document down and up again keeping as much as is still fine.

You do spot that via the hash (or do you mean checksum?). But if a page does change, it would be useful to retain as much information as possible, not just say that the RDF no longer applies. One way to do this is to make sure all elements have unique id's that do not get changed. Or, if a checkpoint refers to a regions of a page, with many elements, that section should be wrapped in a <span> with a unique id. Still have a problem if regions overlap instead of being nested.... hmmm... can xpointer specify regions between two elements?
