Possible values are: `true` (default) or `false`.<br/><br/>`AllowFallback=false` specifies that the translation should only use systems trained for the ‘category’ specified by the request. If a translation for language X to language Y requires chaining through a pivot language E, then all the systems in the chain (X->E and E->Y) will need to be custom and have the same category. If no system is found with the specific category, the request will return a 400 status code. `AllowFallback=true` specifies that the service is allowed to fallback to a general system when a custom system does not exist.
