# TODO(robinson): We should have aggressive checking here,
# for example:
#   * If you specify a repeated field, you should not be allowed
#     to specify a default value.
#   * [Other examples here as needed].
#
# TODO(robinson): for this and other *Descriptor classes, we
# might also want to lock things down aggressively (e.g.,
# prevent clients from setting the attributes).  Having
# stronger invariants here in general will reduce the number
# of runtime checks we must do in reflection.py...
