+// All DOM event targets extend EventTarget. The spec is defined here:

+// the target to which an event is dispatched when something has occurred.
+// All nodes are EventTargets, some other event targets include: XMLHttpRequest,
+// AudioNode and AudioContext.
+
+// To make your class an EventTarget, follow these steps:
+// - Make your IDL interface inherit from EventTarget.
+// - Inherit from EventTargetWithInlineData (only in rare cases should you
+//   use EventTarget directly).
+// - In your class declaration, EventTargetWithInlineData must come first in
+//   the base class list. If your class is non-final, classes inheriting from
+//   your class need to come first, too.
+// - If you added an onfoo attribute, use DEFINE_ATTRIBUTE_EVENT_LISTENER(foo)
+//   in your class declaration. Add "attribute EventHandler onfoo;" to the IDL
+//   file.
+// - Override EventTarget::interfaceName() and getExecutionContext(). The former
+//   will typically return EventTargetNames::YourClassName. The latter will
+//   return ExecutionContextLifecycleObserver::executionContext (if you are an
+//   ExecutionContextLifecycleObserver)
+//   or the document you're in.
+// - Your trace() method will need to call EventTargetWithInlineData::trace
+//   depending on the base class of your class.

+// This class is used to traverse the DOM tree. It isn't meant to be
+// constructed; instead, callers invoke the static methods, after templating it
+// so that ElementType is the type of element they are interested in traversing.
+// Traversals can also be predicated on a matcher, which will be used to
+// filter the returned elements. A matcher is a callable - an object of a class
+// that defines operator(). HasTagName above is an example of a matcher.
+//
+// For example, a caller could do this:
+//   Traversal<Element>::firstChild(some_node,
+//                                  HasTagName(html_names::kTitleTag));
+//
+// This invocation would return the first child of |some_node| (which has to be
+// a ContainerNode) for which HasTagName(html_names::kTitleTag) returned true,
+// so it would return the first child of |someNode| which is a <title> element.
+// If the caller needs to traverse a Node this way, it's necessary to first
+// check Node::IsContainerNode() and then use To<ContainerNode>(). Another way
+// to achieve same behaviour is to use DynamicTo<ContainerNode>() which
+// checks Node::IsContainerNode() and then returns container
+// node. If the conditional check fails then it returns nullptr.
+// DynamicTo<ContainerNode>() wraps IsContainerNode() so there is no need of
+// an explicit conditional check.
+//
+// When looking for a specific element type, it is more efficient to do this:
+//   Traversal<HTMLTitleElement>::firstChild(someNode);
+//
+// Traversal can also be used to find ancestors and descendants; see the
+// documentation in the class body below.
+//
+// Note that these functions do not traverse into child shadow trees of any
+// shadow hosts they encounter. If you need to traverse the shadow DOM, you can
+// manually traverse the shadow trees using a second Traversal, or use
+// FlatTreeTraversal.
+//
