This change does not include any new or change any existing APIs and should not need a Swagger.

@ArcturusZhang, Let me know if you need anything more from my side.

[ArcturusZhang]

LGTM

[ArcturusZhang]

@ruowan could you take a look at the Avocado failure? It looks like an expected failure, do we need to force-merge this?

[akning-ms]

Hi @jennyhunter-msft, Can you also fix the same error in v1/types.json?

[jennyhunter-msft]

Done

[jennyhunter-msft]

Updated the v1 description and updated the v2 to use the same wording found in other documentation about this property
