Table 44describes the details of the ComplexType ServerFacet. This Facet extends the Core ServerFacet to include Variableswith Complex Data, i.e. data that are composed of multiple elements such as a structure and where the individual elements are exposed as component variables. Support of this Facet requires the implementation of structured DataTypes and Variablesthat make use of these DataTypes. The Read, Write and Subscriptions service set shall support the encoding and decoding of these structured DataTypes. As an option the Servercan also support alternate encodings, such as an XML encoding when the binary protocol is currently used and vice-versa.
