• use of Special Symbols page to explain braille dot symbols (5.13, 6.5.1.13)
• non-use of numeric indicator with numbers (6.5.1.1)
• non-use of arrowheads as in print (6.5.1.3, 6.5.2.2)
• alignment of first digit of numeric label with regular scale mark (6.5.1.8, 6.5.2.2)
• use of braille symbol representation instead of tactile graphic (6.5.2.1)
• alignment of horizontal label (YEARS IN TOWN) with first value (0) rather than centered as shown in print (6.5.2.3)
