How do you handle the problem of versioning or changing content with annotations of that content? For example if someone has annotated a piece of text that is changed in the site what is the procedure for dealing with that scenario?

Good question. txtpen uses fuzzy string matching among other anchoring mechanisms. Assuming the change is below a certain threshold, txtpen displays a diff(addition, deletion) of the underlying text.
