+* [http://dev.w3.org/2006/webapi/WebIDL/#ArrayClass The spec of ArrayClass]
+
+Summary: Allows an interface to extend JavaScript arrays.
+
+Usage: [ArrayClass] can be specified on interfaces. An interface may not both have [ArrayClass] and extend another interface.
+
+The bindings for the interface will have the `[[Prototype]]` of the constructor prototype set to `Array.prototype` which means that the methods defined on JavaScript arrays work on the instances of this interface.
