Changes made in Issue 6:
The 1 July 2020 version includes a technical change, namely the introduction of a bar code flag character that indicates the use of ASC MH 10 Data Identifiers with the encoded data.
Other changes are the replacement of the Code 39 by a Code 128 example for a bar coded License Plate, the addition of an example with a 2D Data Matrix encoded License Plate, the addition of a License Plate example with a GS1 Serial Shipping Container Code and a few editorial changes to the text for consistency and improvement of wording.
