[Schevo-devel] Why extent names instead of extent instances?

[Tom Locke]

Hi

Just wondered why you chose to use strings in various places, e.g.

  person.sys.links("PhoneNumber", "person")

As opposed to

  person.sys.links(db.PhoneNumber, "person")

Is it so you can refer to the entity before it has been declared? When 
might that be necessary?
