This structure is used by the client to pass an identification of the measurement to be carried out in a Start method. It is typically not changed by the server and is included in the meta data for identifying a result.

In its basic version here, the MeasIdDataType contains only a TrimmedString. It has been encapsulated in a structure for the purpose of easy sub-typing if more sophisticated identification is required.

A basic MeasIdDataType structure is considered empty when the id member has length 0. For sub-types of MeasIdDataType additional rules may apply., i.e., they shall always be considered empty, when the Id member has length 0, and may also be considered empty when other structure members fulfill particular conditions.
