Agreed in telecon to remove the requirement to set the StructureChange bit when the datatype changes since the datatype is always encoded with the value, so this inforation is redundant. StructureChange bit setting should refer to the case where the data description changes.

Agreed to remove "The bit is also set if the data type Attribute of the Variable changes. A Variable with the data type BaseDataTye does not required the bit to be set when the data type changes."

Removed data type, value rank or array dimension changes from the list of changes setting the StructureChanged bit since this information is always contained in the value.

Change is part of the draft version "OPC UA Part 4 - Services Draft 1.02.02 Body.doc"

Reviewed in telco on March 23, 2011
The final changes are included in the document revision OPC UA Part 4 - Services 1.02.04 Draft.doc

The DataType information is not always provided with the data, only the information needed to en- /decode it.

E.g. enumerations or simple data types are only transfered like Int32 (in case of Enum) or as their base built-in type.

WG September 14 - no further changes needed
