Just thinking out loud..

Maybe you could store the actual information as a special character 
attribute (an invisible style, if you like) and just display a bookmark 
symbol in every line that contains such characters.

What are the semantics of a bookmark? Does a bookmark mark a line 
number? Or the actual content of a line?

As I mentioned before, I think that automatic bookmarks (based on 
language-specific regex) are way superior to custom bookmarks: Their 
behaviour is well-defined, and they can be calculated on the fly (no 
need to store file metadata).
