The Foreword provides background on the standards process for X3D language bindings. The Introduction describes the purpose of X3D language bindings. The following clauses define this part of ISO/IEC 19777:

1. Scope defines the problem area that the ECMAScript language binding of X3D addresses.
2. Normative references lists the normative standards referenced in this part of ISO/IEC 19777.
3. Concepts describes various fundamentals of the ECMAScript language binding of X3D.
4. Tables describes the mapping between abstract names and bound names.
5. Type definitions specifies the binding of abstract data types to ECMAScript data types.
6. Function definitions specifies binding of abstract service and function definitions to ECMAScript function definitions.

There are two annexes included in the specification:

1. Relationship to ISO/IEC 14772 describes the relationship to features of VRML 97
2. Examples includes a variety of ECMAScript bound example files.
