 ### Q: Does rjsf support `oneOf`, `anyOf`, multiple types in an array, etc.?
 
-A: Not yet (except for a special case where you can use `oneOf` in [schema dependencies](#schema-depdencies)), but perhaps you will be the person whose PR will finally add the feature in a way that gets merged. For inspiration, see [#329](https://github.com/mozilla-services/react-jsonschema-form/pull/329) or [#417](https://github.com/mozilla-services/react-jsonschema-form/pull/417).
