+\section{Scope}
+\label{ecmaScope}
 
-\subsection{Licensing}
-\label{licensing}
+This Ecma standard specifies the syntax and semantics of the Dart programming language.  It does not specify the APIs of the Dart libraries except where those library elements are essential to the correct functioning of the language itself (e.g., the existence of class \cd{Object} with methods such as \cd{noSuchMethod}, \cd{runtimeType}).
+
+\section{Conformance}
+\label{ecmaConformance}
+
+A conforming  implementation of the Dart programming language must provide and support all the  APIs (libraries, types, functions, getters, setters, whether top-level, static, instance or local) mandated in this specification. 
+
+A conforming implementation is permitted to provide additional APIs, but not additional syntax, except for experimental features in support of enumerated types and deferred loading which are expected to be added in the next revision of this specification.
+
+% A claim of conformance with this Ecma Standard shall specify?
+
+\section{Normative References}
+\label{ecmaNormativeReferences}
+
+The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
+
+\begin{enumerate}
+\item
+The Unicode Standard, Version 5.0, as amended by Unicode 5.1.0, or successor.
+\item
+Dart API Reference, https://api.dartlang.org/

+A library that implements the [JSON-RPC 2.0 spec][spec].
+
+[spec]: http://www.jsonrpc.org/specification
+
+## Server
+
+A JSON-RPC 2.0 server exposes a set of methods that can be called by clients.
+These methods can be registered using `Server.registerMethod`:
+
+```dart
+import "package:json_rpc_2/json_rpc_2.dart" as json_rpc;
+
+var server = new json_rpc.Server();
+
+// Any string may be used as a method name. JSON-RPC 2.0 methods are
+// case-sensitive.
+var i = 0;
+server.registerMethod("count", () {
+  // Just return the value to be sent as a response to the client. This can be
+  // anything JSON-serializable, or a Future that completes to something
+  // JSON-serializable.
+  return i++;
+});
+
+// Methods can take parameters. They're presented as a [Parameters] object which
+// makes it easy to validate that the expected parameters exist.
+server.registerMethod("echo", (params) {
+  // If the request doesn't have a "message" parameter, this will automatically
+  // send a response notifying the client that the request was invalid.
+  return params.getNamed("message");
+});
+
+// [Parameters] has methods for verifying argument types.
+server.registerMethod("subtract", (params) {
+  // If "minuend" or "subtrahend" aren't numbers, this will reject the request.
+  return params.getNum("minuend") - params.getNum("subtrahend");
+});
+
+// [Parameters] also supports optional arguments.
+server.registerMethod("sort", (params) {
+  var list = params.getList("list");
+  list.sort();
+  if (params.getBool("descending", orElse: () => false)) {
+    return params.list.reversed;
+  } else {
+    return params.list;
+  }
+});
+
+// A method can send an error response by throwing a `json_rpc.RpcException`.
+// Any positive number may be used as an application-defined error code.
+const DIVIDE_BY_ZERO = 1;
+server.registerMethod("divide", (params) {
+  var divisor = params.getNum("divisor");
+  if (divisor == 0) {
+    throw new json_rpc.RpcException(DIVIDE_BY_ZERO, "Cannot divide by zero.");
+  }
+
+  return params.getNum("dividend") / divisor;
+});
+```
+
+Once you've registered your methods, you can handle requests with
+`Server.parseRequest`:
+
+```dart
+import 'dart:io';
+
+WebSocket.connect('ws://localhost:4321').then((socket) {
+  socket.listen((message) {
+    server.parseRequest(message).then((response) {
+      if (response != null) socket.add(response);
+    });
+  });
+});
+```
+
+If you're communicating with objects that haven't been serialized to a string,
+you can also call `Server.handleRequest` directly:
+
+```dart
+import 'dart:isolate';
+
+var receive = new ReceivePort();
+Isolate.spawnUri('path/to/client.dart', [], receive.sendPort).then((_) {
+  receive.listen((message) {
+    server.handleRequest(message['request']).then((response) {
+      if (response != null) message['respond'].send(response);
+    });
+  });
+})
+```
+
+## Client
+
+Currently this package does not contain an implementation of a JSON-RPC 2.0
+client.

+## Stack Chains
+
+This library also provides the ability to capture "stack chains" with the
+`Chain` class. When writing asynchronous code, a single stack trace isn't very
+useful, since the call stack is unwound every time something async happens. A
+stack chain tracks stack traces through asynchronous calls, so that you can see
+the full path from `main` down to the error.
+
+To use stack chains, just wrap the code that you want to track in
+`Chain.capture`. This will create a new [Zone][] in which stack traces are
+recorded and woven into chains every time an asynchronous call occurs. Zones are
+sticky, too, so any asynchronous operations started in the `Chain.capture`
+callback will have their chains tracked, as will asynchronous operations they
+start and so on.
+
+Here's an example of some code that doesn't capture its stack chains:
+
+```dart
+import 'dart:async';
+
+void main() {
+  scheduleAsync();
+}
+
+void scheduleAsync() {
+  return new Future.delayed(new Duration(seconds: 1))
+      .then((_) => runAsync());
+}
+
+void runAsync() {
+  throw 'oh no!';
+}
+```
+
+If we run this, it prints the following:
+
+    Uncaught Error: oh no!
+    Stack Trace: 
+    #0      runAsync (file:///usr/local/google-old/home/goog/dart/dart/test.dart:13:3)
+    #1      scheduleAsync.<anonymous closure> (file:///usr/local/google-old/home/goog/dart/dart/test.dart:9:28)
+    #2      _rootRunUnary (dart:async/zone.dart:717)
+    #3      _RootZone.runUnary (dart:async/zone.dart:854)
+    #4      _Future._propagateToListeners.handleValueCallback (dart:async/future_impl.dart:488)
+    #5      _Future._propagateToListeners (dart:async/future_impl.dart:571)
+    #6      _Future._complete (dart:async/future_impl.dart:317)
+    #7      _SyncCompleter.complete (dart:async/future_impl.dart:44)
+    #8      Future.Future.delayed.<anonymous closure> (dart:async/future.dart:219)
+    #9      _createTimer.<anonymous closure> (dart:async-patch/timer_patch.dart:11)
+    #10     _handleTimeout (dart:io/timer_impl.dart:292)
+    #11     _RawReceivePortImpl._handleMessage (dart:isolate-patch/isolate_patch.dart:115)
+
+Notice how there's no mention of `main` in that stack trace. All we know is that
+the error was in `runAsync`; we don't know why `runAsync` was called.
+
+Now let's look at the same code with stack chains captured:
+
+```dart
+import 'dart:async';
+
+import 'package:stack_trace/stack_trace.dart';
+
+void main() {
+  Chain.capture(() {
+    scheduleAsync();
+  });
+}
+
+void scheduleAsync() {
+  new Future.delayed(new Duration(seconds: 1))
+      .then((_) => runAsync());
+}
+
+void runAsync() {
+  throw 'oh no!';
+}
+```
+
+Now if we run it, it prints this:
+
+    Uncaught Error: oh no!

+
+That's a lot of text! If you look closely, though, you can see that `main` is
+listed in the first trace in the chain.
+
+Thankfully, you can call `Chain.terse` just like `Trace.terse` to get rid of all
+the frames you don't care about. The terse version of the stack chain above is
+this:
+
+    test.dart 17:3   runAsync
+    test.dart 13:28  scheduleAsync.<fn>
+    dart:isolate     _RawReceivePortImpl._handleMessage

+    dart:isolate                              _RawReceivePortImpl._handleMessage
+
+That's a lot easier to understand!
+
+### `Chain.track`
+
+For the most part `Chain.capture` will notice when an error is thrown and
+associate the correct stack chain with it. However, there are some cases where
+exceptions won't be automatically detected: any `Future` constructor,
+`Completer.completeError`, `Stream.addError`, and libraries that use these such
+as `dart:io` and `dart:async`. For these, all you need to do is wrap the Future
+or Stream in a call to `Chain.track` and the errors will be tracked correctly.
