Example with null value

[jdeboer-geoplan]

Feature Request:

I think this is a feature request as I don't think there is a way of doing this.

I would like

    /// <summary>
    /// blah blah blah
    /// </summary>
    /// <example>null</example>
    public int? NullableInt{ get; set; }

to produce:

      "nullableInt": {
        "type": "integer",
        "description": "blah blah blah",
        "format": "int32",
        "nullable": true,
        "example": null
      },

At the moment it does not produce an example and the swaggerUI gives it a 0.

I've got round this by implementing an ISchemaFilter based on XmlCommentsSchemaFilter which looks for the word "null" and sets the example to OpenApiNull(), but I wonder if this'd be good to have in the real XmlCommentsSchemaFilter or if I've missed something obvious to avoid having to do this.
