Usage of API fields that have the prefix "unsupported” or undocumented annotations
Select APIs in the product expose fields with the prefix unsupported<FieldName>. No assurances are made at this time that usage of this field is supported across releases or within a release. Product support can request a customer to specify a value in this field when debugging specific problems, but its usage is not supported outside of that interaction. Usage of annotations on objects that are not explicitly documented are not assured support across minor releases.
