scope:

This Part of CWA 14838 should be read after Part 1 and 2. It is intended for readers who require guidance and stimulation for drafting specifications for business and technical processes for smart card casedticketing schemes that are intended to be interoperable with other schemes according to the multi-operator scenarios and fare product types proposed in CWA 14838-1 and -2. It is therefore assumed in this Part that the reader will not require any futher guidance on the motivation or rationale of such schemes. If they do, they should look again at the earlier parts of the CWA.
