+// features, on a per-origin basis (origin trials). This class provides the
+// implementation to check if the experimental feature should be enabled for the
+// current context.  This class is not for direct use by feature implementers.
+// Instead, the OriginTrials generated class provides a static method for each
+// feature to check if it is enabled. Experimental features must be defined in
+// RuntimeEnabledFeatures.in, which is used to generate OriginTrials.h/cpp.
+//
+// Experimental features are defined by string names, provided by the
+// implementers. The EF code does not maintain an enum or constant list for
+// feature names. Instead, the EF validates the name provided by the feature
+// implementation against any provided tokens.
+//
+// This class is not intended to be instantiated. Any required state is kept
+// with a WebApiKeyValidator object held in the Platform object.
+// The static methods in this class may be called either from the main thread
+// or from a worker thread.
