Looking good so far - cloned it locally, I'll add a few commits to this PR and then request a review from f0x.

There is something wrong. The BaseTagSerializer require a TagEncoder to fetch the tag. So it can't be used in other formats. So the serializers should be internal or implement a standalone parser for serializer.
