RLS11 — Data Format definitions

Data formats that each Interface::Stream can handle are defined in Interface::StreamAbility. dataFormat. However, in certain cases, data formats may be automatically handled by middlewares. We shall reconsider to what extent data formats are treated as part of the RLS specification. Also, definition of each data format is currently not described. As other parts, such as coordinate reference system definitions, specification for describing data format definitions shall be defined.
