discriminatorValue not recognized if declared in sub-sub-type (warning)

[leflamm]

Hi,
it seems like discriminatorValues are not recognized if declared in a sub-sub-type (neither default nor explicitly defined).

api-designer rises warning:
WARNING: None of the 'A' type known subtypes declare 'C' as discriminating property 'kind'.
