Output contains a lot of "anyOf" with just one item about odata-openapi

[ralfhandl]

Hi @IvanGoncharov,

Unfortunately this is necessary to combine nullable with $ref, and I‘m basically following your advice from OAI/OpenAPI-Specification#556 (comment).

I use anyOf instead of allOf because I use the same construct with properties that can be numbers or strings, e.g.

odata-openapi/examples/People.openapi3.json

Lines 1411 to 1423 in 48bd0c5

	"TotalExpense": {
	"anyOf": [
	{
	"type": "number"
	},
	{
	"type": "string"
	}
	],
	"format": "decimal",
	"multipleOf": 1,
	"example": 0
	}

Any less verbose solution to this problem is highly welcome.

Thanks in advance
Ralf

@IvanGoncharov Thanks for detail reply 👍

@IvanGoncharov In the meantime I switched to oneOf in cases that contain only one item because this is represented nicer in Swagger UI.
