The following topics describe several SOM-unique extensions of the standard CORBA syntax that are permitted by SOM IDL for convenience. These constructs can be used in an .idl file without generating a SOM Compiler error.
If you want to verify that an IDL file contains only standard CORBA specifications, the SOM Compiler option -mcorba turns off each of these extensions and produces compiler errors wherever non-CORBA specifications are used. (The SOM Compiler command and options are described in the topic "Running the SOM Compiler" later in this chapter.)
