Rationale for Correction:​

TID 1500 requires a Language, Procedure Reported, an empty section (CONTAINER) for the Image Library, and both Tracking​
Identifier and Unique Identifier, all of which complicate the "simplest" example used in Sup 219 (JSON).​
It is proposed to modify TID 1500 to relax these requirements that are not needed for many simple AI/ML use cases for which the​
information is either not available or unnecessary. E.g., it would be harmless to omit an empty Image Library CONTAINER). and​
Procedure Reported may not be known and will often be a dummy value based on Modality only, and the Language is irrelevant for​
measurements (though not for code meanings of coded concepts, but could be assumed or just left unstated). The Tracking Identifier​
and Unique Identifier are not needed when there is only one lesion and no temporal change tracking is needed for the use case.​
