C2MS11 — Rework Individual Message Header Tables

Each message includes a "[message name] Header table that repeats header field definitions as already listed in Table 8-3 Message Header Additional Information. Instead, this individual message table is intended to show what special values are applied to certain fields of the header. This needs to be made more clear, without duplicating information in the already-existing Header table. In other words, these tables should provide unique-to-the-message values rather than repeating header definitions.

A specific example of why this is not practical is that the existing set of tables all show the HEADER-VERSION 2019. Because the HEADER-VERSION is being updated in 1.1, each of these 31 tables must also be updated. In order to avoid this kind of issue in the future, these tables need to be reduced to just the necessary message-specific values.

See for example, "Table 8-108 Mnemonic Value Data Message Header". This table does not need to include the "Notes" column, since that is simply repeating word-for-word what exists elsewhere, and should not include the HEADER-VERSION row, since that is defined elsewhere, including its value.

To make this better, change the column name of column one to "Header Field Name". Additionally, should change the table title to "Table 8-108 Mnemonic Value Data Message Header Values".
