Also, am I correct in saying that if you delete a tag from one version to another, and then if you revert to the previous version, you'll loose the tag?

Yes, you are correct.\\ You're seeing the Tag as a concept that relates with the various version numbers independently and I'm seeing the Tag with associated to the conceptual entry, independent from its version number.\\
I see things the that way because to me Tags aren't version dependent.
