GS1 Composite Symbols: Remove the page, its content being on the composite and CC pages
GS1 Composite symbologies: Give each symbology its own page, leaving the 2D components
Symbologies: corrections from a review against the code and specifications; more uses; undocumented options
EAN-13, UPC-A, EAN-8: Drop the scanner transmission detail; GTIN zero-fill belongs to AI (01)
Symbologies: their uses, and add-on, sequence variant and error correction notes
Uses: lines on the pages that had none, for the uses people look a
symbology up by (postal services, healthcare and pharmacy codes,
libraries, coupons, payment slips, add-ons, GS1 DataBar), and on Code 128,
Code 39, Data Matrix, EAN-13 and UPC-A for ISBT 128, AIAG B-10, IUID,
securPharm IFA, EIGP 114 and restricted circulation numbers. GS1 Data
Matrix names DSCSA beside the Falsified Medicines Directive.
EAN-5 gives the book price add-on's meanings, EAN-2 the issue number,
ISSN that the sequence variant is optional, and QR Code what the error
correction level trades.
