Schema array type with anyOf and discriminator fails validation #402
Description
I'm trying to validate an OpenAPI document that contains a schema object that is of type 'array' that can be an 'anyOf' that uses a discriminator to know which object goes into the array and it's failing validation. The document appears to be a valid OAS3 document and the Swagger UI has no issues rendering it, so I'm guessing it's an issue with OpenAPI.NET.
I'm getting validation errors similar to:
Composite Schema ChildTypeA must contain property specified in the discriminator type. [#/components/schemas/SampleResponse/properties/suggestedActions/items/anyOf]
Composite schema ChildTypeA must contain property specified in the discriminator type in the required field list. [#/components/schemas/SampleResponse/properties/suggestedActions/items/anyOf]
