AllOf not generated

[NickRandal]

Using 3.0.16

schema.AllOf.Add(
			new JSchema
			{
				Description = "Path is required when using the Custom step type.",

				If = new JSchema
				{
					Properties =
					{
						{ "StepType", new JSchema { Const = Configuration.StepType.Custom.ToString() } }
					},
					Required = { "StepType" }
				},
				Then = new JSchema
				{
					Required = { "Path" }
				}
			}
		);

Produces

"allOf": [
        {
          "description": "Path is required when using the Custom step type."
        }
      ]

This ultimately was my mistake because I had chosen Draft 06 version instead of the required 07.

Knowing that would it be possible to have an exception thrown when If, Else or Then are not null and Draft 07 is not in use?
