The patch seems fine, however I have a question.

>From what I got about the issue:
- it seems perfectly legal to add two tags of the identical type. It's up to
the Tag Reader and Tag writer to prove and maintain tags uniqueness (when
needed).

>From a design point of view, shouldn't it better to add a property to the tags
"unique", so to (if the tag is marked unique:
- when the tag is added, discard or overwrite the old one.

This approach would fix to the boots the issue, also for future tags. Moreover
is more foolproof. The cons is a slightly increased overhead when adding a tag.

Cheers,

T.
