oneof property with null value

[Valery-vs]

Hi
How can I create schema with oneof property which could be null value?

Here is the part of schema that describes what you want:

{
  "oneOf": [{
    "type": "string",
    "enum": ["something"],
    "title": "A non null value"
  }, {
    "type": "null",
    "enum": [null],
    "title": "A null value"
  }]
}
