This module defines the Label data structures read by CSParser.c. Applications will
include this if they want direct access to the data (as opposed to using iterator
methods).
The following data structures relate to the data encapsulated in a PICS Label. Each
data type correlates to a time in the BNF for the label description. See PICS Labels
spec for more details.
