The Property DataTypeVersion is explained in D.3.
The NamespaceUri is the URI for the namespace described by the Value Attribute of the DataTypeDictionary. This is not always the same as the NamespaceUri of the DataType NodeId.
The Deprecated Property is used to indicate that all of the DataType definitions represented by the DataTypeDictionaryType are available through a DataTypeDefinition Attribute. Servers that provide DataType definitions as a DataTypeDefinition Attribute and through a DataTypeDictionaryType shall expose this Property.
