Chapter 9.2.3.1 states the following:

The definition on a variable instance is using the MultiStateDiscreteType Variable Type which defines
also the EnumStrings or the EnumValues Property containing the enumeration values as string array.
This is not correct as the EnumValues is defined by MultiStateValueDiscreteType and neither of them
is a string array.

Table 29 contains incorrect definitions.

HasProperty | Variable | EnumString | String [ ] | PropertyType | Optional
HasProperty | Variable | EnumValues | EnumValueDataType [ ] | PropertyType | Optional
Datatype String[ ] for EnumString is not correct. OPC 10000-3 defines this as LocalizedText[ ]
Modellingrule Optional is not correct. OPC 10000-8 defines both as mandatory.

Following references are made:

The Property EnumString is defined in OPC 10000-5
The Property EnumValues is defined in OPC 10000-5.
Those are also wrong as both properties are defined in OPC 10000-3.

Addendum:
If usage of MultiStateValueDiscreteType was intended, the property ValueAsText has to be added somewhere. This is a mandatory property for MultiStateValueDiscreteType. Too me this chapter lacks substantially.
