Bookmark is just a string; one hack you can do is to give it a unique
name, which refers to a per-document custom metadata, where the value
disturbs the user less. But that's still just a string, so you need to
serialize/load to/from string if you want to store key-value pairs.
An alternative is to use RDF annotations, which allows more complex
(Though you need to use archive.org or something like that to access it,
seems the Apache site is currently not available.)
One shortcoming of RDF is that it's ODF-only; while the per-doc custom
metadata + bookmarks works with most other formats as well.

I would prefer a solution without the search step, but I don't know how to get a valid XTextRange (I admit I don't yet well understand the behavior of the API).
> Please, do you have some pointer or code example ?
Some kind of iteration or search is necessary: if you take the user's
current selection or you iterate to the nth paragraph or you search for
text is up to you. An XTextRange is just a selection (where start and
end may point to the same document model position).

Hope this helps. :-)
