Yes.

That's more or less what TagTree is.

Not necessarily. If you have a flat serialization (such as XML) the
nested structure isn't needed. Of course that's not a fully normalized
relational representation, but if you had one, how often would it be
used, how efficient would those queries be (SQL is poor at nested or
recursive data structures), and how much pain would it be to write the
object-relational mappings?
