// AST_Fields denote fields in IDL structure, union and exception
// declarations. AST_Field is also used as a superclass of AST_Argument
// and AST_UnionBranch.
// AST_Fields have a field type (a subclass of AST_Type) and a name
// (a UTL_ScopedName).

// AST_Field supplies two constructors, one to be used in constructing
// AST_Field nodes, the other to be used in constructing AST_Argument
// nodes and AST_UnionBranch nodes.
