// Enum for the state of a given caption property
enum CaptionState {
// The property is not supported by the system. The application should provide
// a way to set this property, otherwise it will not be changeable.
// The property is supported by the system, but the user has not set it.
// The application should provide a default setting for the property to
// handle this case.
// The user has set this property as a system default, meaning that it should
// take priority over app defaults. If SystemCaptionSettings.supportsOverride
// contains true, this value should be interpreted as explicitly saying
// "do not override." If it contains false, it is up to the application to
// intepret any additional meaning of this value.
// This property should take priority over everything but application-level
// overrides, including video caption data. If
// SystemCaptionSettings.supportsOverride contains false, then no attributes
// will ever contain this value.
