The extensible parameter types can only be extended by additional parts of OPC 10000.

The ExtensibleParameterdefines a data structure with two elements. The parameterTypeIdspecifies the data type encoding of the second element. Therefore the second element is specified as “--“. The ExtensibleParameterbase type is defined in Table 142.

Concrete extensible parameters that are common to OPC UA are defined in Clause 7. Additional parts of OPC 10000 can define additional extensible parameter types.
