Allow nullable references

Are you sure the spec allows this? My understanding of the Reference Object is that it doesn't:

This object cannot be extended with additional properties and any properties added SHALL be ignored.

FWIW, I seem to recall an ugly hack to work around this restriction. Something like:

NullableThingy:
    nullable: true
    oneOf:
        - $ref: "#/components/schemas/Thingy"

Note that this restriction on additional properties is a difference between Reference Objects and Schema Objects that contain a $ref keyword.

I see, so my problem actually seems to be that something gets interpreted as a Reference object instead of as a Schema object (since that allows nullable together with $ref).

Ok this is a specific bug in my application. Thanks for your help!
