For the convenience of direct addressing to the root object of the module from any object lower in the hierarchy, it is recommended to define the global variable "mod" in the namespace of the module, with its initialization in the constructor of the root object. Also, for transparent translation of the text messages of the module, it is recommended to define the function templates of the module message translation call "_({Message})" and "trS({Message})" as:

#undef _
#define _(mess) mod->I18N(mess).c_str()
#undef trS
#define trS(mess) mod->I18N(mess,mess_PreSave)
