### Reason why this change is needed

* This may be a direct copy from the issue.

### Description of the change

* Describe what is done.

### Affected operating points

* Describe here as well as possible what operating points are affected and how

* In minimum, there should be a status for bitstream compatibility and output bit exactness

* For bitstream compatibility, the following levels are helpful for describing encoder

  1. Produced bitstream is BE compared to previous state.

  2. Produced bitstream is non-BE but it is fully backwards compatible for decoding. Decoded output may differ.

  3. Produced bitstream is non-BC. Old decoder cannot decode the produced bitstream correctly.

* For output difference, use BE or non-BE. Additionally, amount of difference can be presented.
