This part of ISO/IEC 13719 defines the standard binding of the Portable Common Tool Environment (PCTE), as specified in ISO/IEC 13719-1, to the CORBA Interface Definition Language (IDL) defined in ISO/IEC CD 14750.

A number of features are not completely defined in ISO/IEC 13719-1, some freedom being allowed to the implementer. Some of these features are specified as implementation limits. Some constraints are placed on these implementation limits by this IDL Binding Standard. These constraints are specified in clause 24, Implementation Limits.

PCTE is an interface to a set of facilities that forms the basis for constructing environments supporting systems engineering projects. These facilities are designed particularly to provide an infrastructure for programs which may be part of such environments. Such programs, which are used as aids to systems development, are often referred to as tools.
