1) Table 24, "Uncertain": "At least one Variable in ExpectedVerificationVariables and/or ExpectedAdditionalVerificationVariables failed verification (i.e. StatusCode != Good) and VerificationVariablesErrors and/or VerificationAdditionalVariablesErrors are populated."
2) AssetCompatibility.NotSet: "VerificationVariablesErrors and/or VerificationAdditionalVariablesErrors shall be populated."
3) Table 24 contains the method result code "Uncertain", which is returned if at least one of the variables failed verification. This is only the case for NotSet, Mismatch and Compatible, which in turn means that for all of these, the output arrays must be populated. If this is true, the sentence about populating the output arrays can be removed from NotSet.
This would also mean, that if the method returns "Good", verification must have resulted in a Match.
