No-op semantic actions for vrml97_grammar.
This struct includes a no-op function for each semantic action called by vrml97_grammar. It is the default value of vrml97_grammar%'s Actions template parameter. It is generally convenient to inherit this struct when providing your own semantic actions, as doing so will provide a default no-op action where none has been implemented or none needs to occur.
