In SVN there really is no technical difference between a tag and a branch IIRC, although their intended usages are different, as you say.

To the point where it's almost easiest to say SVN doesn't have branches or tags - it just has directories and conventions.
Git doesn't really have a technical difference between a tag and a branch either. They are both files containing a hash for some commit. Tags are just more cumbersome to move (branches are moved on new commits), and they can be signed cryptologically(is that a word?).
