Reported by Kenneth Lee:

• There is no "Call-Service" in OPC 10000-4, only "Call Service"
• Figure 2: “re-certification” typically doesn’t have “-“
• Figure 2, at the bottom: “OPC Call” might be better to be replaced by “OPC Call Service”
• Figure 2, at the bottom: “Call-Service of the Method Service Set” may need to be removed as this is applicable only for Client/Server
• Page 26 – extra space between contains and methods

Reported by Herbert Barthel:
Table 34 - SafetyConsumer transitions:

• word "TRANSITION" not centered in column 1
• consider making border smaller (0,19 to 0,1 cm) for columns 1 to 3
• make ACTIVITY column broader (so "0" in T18 is not wrapped into new line, as is "1" in T22)
• superfluous tabs in if-then-else branches in T22
• IEC 61784-3 does not have full stops in sentences in tables
  Table 38 - Examples for cryptographically [...]:
• use "keep with next" in paragraph options
