Moreover, in §3.3 of the part 5 revision 1.03, Table 1 contains examples of DataTypes with ValueRank > 0 and ArrayDimensions can be omitted. This is very confusing.

Changed Variable descripition of ArrayDimensions in Table 5 to:

"If the ValueRank does not identify an array of a specific dimension (i.e. ValueRank <= 0) the ArrayDimensions can either be set to null or the Attribute is missing. This behaviour is server-specific.
If the ValueRank specifies an array of a specific dimension (i.e. ValueRank > 0) and the Server can determine dimension size, then the ArrayDimensions Attribute shall be specified with the definition of the Variable. If the Server cannot determine the exact size of the dimension it shall be set to 0 or omitted."

After review the WG determined that Table 5 is specific to Nodes define in the 10000 series specs and not a general statement.
Therefore no change is needed.

The context is missing - what are the 10000 series specs?

Table 5 says "For all Variables specified in this standard, the Attributes named in Table 5 shall be set as specified in Table 5. " I interpret that it applies to all variables.

The spec should be clear and unambiguous and not require information not contained in the spec.

Agreed to change "in the 10000 series" to "defined in namespace index 0".

change references in clause 5 from "the OPC 10000 series of documents" to "NamespaceIndex 0".

Agreed to changes in Virtual F2F.
