The <apply-trap> class implements traps that are triggered upon any procedure application. No further parameters are needed to specify an instance of this class, so there are no class-specific trap options. Note that it remains possible to use the common trap options (see Common Trap Options), for example to set a trap for the next application where some condition is true.
