The Foreword provides background on the standards process for VRML. The Introduction describes the purpose, design criteria, and characteristics of VRML. The following clauses define part 4 of ISO/IEC 14772:

1. Scope defines the problem area that VRML addresses.
2. Normative references lists the normative standards referenced in this part of ISO/IEC 14772.
3. Definitions contains the glossary of terminology used in this part of ISO/IEC 14772.
4. Concepts describes various fundamentals of VRML.
5. Encoding of fields specifies the XML encoding of datatypes used by nodes.
6. Encoding of nodes defines the XML encoding of VRML nodes.
7. Encoding of other entities defines the XML encoding of other VRML statements.
8. Conformance describes the conformance requirements for VRML implementations.

There are several annexes included in the specification:

1. Grammar definition presents the grammar for the VRML XML encoded file format.
2. Schema for data types presents the description of VRML data types in XML schema.
3. Examples includes a variety of VRML example files.
