1.3 Overview
This structure provides a compact way to serialize one or more property sets. Each property set consists of a property set identifier and one or more property values. Each property value consists of a unique property name and an associated value. Each property name can be either an unsigned integer or, in the case of a special property set identifier, a Unicode string.
This structure does not specify the semantics of properties or the assignment of property set identifiers or property names.
Data in this file format is stored in little-endian format.
