Modules

The .EXTEND keyword is used to extend an existing syntax definition with new rules. It is followed by an identifier for the syntax definition to be extended. The syntax definition must be declared in the same file or - if using modules - must appear in the file that imports the module or was imported by the module.

Please note that the .EXTEND keyword may only be used outside the original .SYNTAX definition.
