A number of changes are required to the Market Message Implementation guides to ensure clarity and accuracy.

1. Common Data Segments: Treatment of Technical Contact details is incorrect. This comprises a Contact

name (field), Technical Contact Details (Segment) and Technical Contact Address (Segment) – it is

currently treated as a single segment in this guide. See Draft v 4.1.1 of guide issued on 19 May 2004 by C Madden.

2. Customer Data and Agreements: The effective date for each type of customer detail change (notified on message 013) should be included in the guide.

3. Data Aggregation: Changes to cardinality of 115 and 115R messages from 1…N to 1.

4. Data Processing : A number of minor corrections and clarifications to the text are required. See Draft v

4.1.1 of guide issued on 19 May 2004 by C Madden.
