The following constitute non-substantive V2 changes:
- Changes to the codes in user defined and externally defined tables.
- Changes to definitions (segment, element, trigger event, data type, etc.) that clarify the WG’s intent rather than changing subsequent processing.
- Technical corrections that implement the original intent of the WG. For example, if a WG meant to add an attribute to one segment, and it was mistakenly added to another; this can be corrected without an additional ballot.
- Changes to the HL7 assigned ID for an element when it is realized that what appears to be a new element is an existing one.
