Standard/IG: Implementation Guide	Artifact ID, Name: Message Structure: Brackets for RE elements

Issue

1. P 45ff For the M10 and MO8 messages the OM4 has square brackets and since element is RE need to remove them.
2. For the M04 message NTE segment has square brackets and is listed as RE. Is this supposed to be O or RE if RE then NTE segment is not defined in IG.

Background: " 2.12.1 Message representation For each trigger event the messages that are exchanged when the trigger event occurs are defined using the HL7 abstract message syntax as follows: Each message is defined in special notation that lists the segment IDs in the order they would appear in the message. Braces, { . . . }, indicate one or more repetitions of the enclosed group of segments. Of course, the group may contain only a single segment. Brackets, [ . . . ], show that the enclosed group of segments is optional.... "

Recommendation

1. Remove square bracket from OM4 segment for the M10 and MO8 messages.
2. List NTE segment as O in the MO4 message structure.

Rationale

Conform to message representation rules in base standard.
