That's a good point. One advantage to doing it this way is your objects
do not *necessarily* need to know anything about the actual parsing
mechanism. You can call an object parser that parses out the required
attributes and entities on behalf of the object, and then call normal
object methods to get it into the state you want.

Both ways could be utilized trivially.
