/*

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.
