So parameter filters collection has two components out of the box. The springmvc-native information that it can gather and the custom/swagger annotations that layer on top of this. So There is a [ParameterFilter](https://github.com/alexeytokar/swagger-springmvc/blob/master/src/main/java/com/mangofactory/swagger/spring/filters/ParameterFilter.java) and an [AnnotatedParameterFilter](https://github.com/alexeytokar/swagger-springmvc/blob/master/src/main/java/com/mangofactory/swagger/filters/AnnotatedParameterFilter.java#L76-L84). In addition you could customize this list (add/remove) to suit your own needs. This does not seem like the right place for this, mainly because this class is not supposed to know about annotations that are not intrinsic to springmvc.
