// ContextData is an interface that supports a simple API to verify whether
// a given context has Controlled Frame capability. One part of that check is
// to ensure that the context is isolated while in some instances the other
// part is to check if the Controlled Frame permissions policy is enabled.
//
// ContextData is used as a base class for FrameContextData, which is an
// abstract class that's used by concrete classes to implement both the
// ContextData and FrameContextData APIs. This class allows browser- and
// renderer-based code to implement these APIs based off of different underlying
// types, like RenderFrameHost vs RenderFrame.
// TODO(b/267673751): Adjust ContextData to hold more data.
