public sealed class FeatureSetDefaults : IMessage<FeatureSetDefaults>, IEquatable<FeatureSetDefaults>, IDeepCloneable<FeatureSetDefaults>, IBufferMessage, IMessage
A compiled specification for the defaults of a set of features. These
messages are generated from FeatureSet extensions and can be used to seed
feature resolution. The resolution with this object becomes a simple search
for the closest matching edition, followed by proto merges.
