        Identifiers

        Many Prompto objects are uniquely identified by a built-in or user defined name: attributes, categories, methods, variables and so forth.

        Type names

        Prompto supports both built-in types and user defined types.

            The name of a type must start with an uppercase letter, followed by 0 or more letter, digit or underscore.

            The formal definition is 'A'..'Z' ('a'..'z' | 'A'..'Z' | '0'..'9' | '_')*.
            

                Text is a valid type name
                TEXT is not a valid type name (it's a symbol)
                text is not a valid type name
            
        

        Attribute names

        Prompto supports attributes.

            The name of an attribute must start with a lowercase letter, followed by 0 or more letter, digit or underscore.

            The formal definition is 'a'..'z' ('a'..'z' | 'A'..'Z' | '0'..'9' | '_')*.
            

                dateOfBirth is a valid attribute name
                DateOfBirth is not a valid attribute name
            
        

        Variable names

        Prompto supports variables.

            The name of a variable must start with a lowercase letter, followed by 0 or more letter, digit or underscore.

            The formal definition is 'a'..'z' ('a'..'z' | 'A'..'Z' | '0'..'9' | '_')*.
            

                someItem is a valid variable name
                SomeItem is not a valid variable name
            
        

        Method names

        Prompto supports methods.

            The name of a variable must start with a letter, followed by 0 or more letter, digit or underscore.

            The formal definition is ('a'..'z' | 'A'..'Z')('a'..'z' | 'A'..'Z' | '0'..'9' | '_')*.
            

                someMethod is a valid method name
                SomeMethod is a valid method name
                SOME_METHOD is not a valid method name
            
        

        Symbol names

        Prompto supports enumerations of both built-in types and user defined types.

            The name of an enumerated value is called a symbol. It must start with an uppercase letter, followed by 0 or more uppercase letter, digit or underscore.

            The formal definition is 'A'..'Z' ('A'..'Z' | '0'..'9' | '_')*.
        

            NORTH is a valid symbol
            North is not a valid symbol
