SimpleSchema.oneOf uses only last sub schema.

[TheGame2500]

Tried using SimpleSchema.oneOf with sub schemas (I know, bad idea considering the kindly written note that it's experimental).

It seems like it's only using the last schema fed in for validation, as can be seen with the following snippets :

Snippet 1 :

var sampleSchema = new SimpleSchema({
	property : SimpleSchema.oneOf(
	new SimpleSchema({
		subProperty : String,
	}),
	new SimpleSchema({
		subProperty : Number,
	}))
})

sampleSchema.validate({
	property : {
		subProperty : 1,
	}
}) // OK

sampleSchema.validate({
	property : {
		subProperty : 'stringy string',
	}
}) // ClientError: Sub property must be of type Number

Snippet 2 :

var sampleSchema = new SimpleSchema({
	property : SimpleSchema.oneOf(
	new SimpleSchema({
		subProperty : Number,
	}),
	new SimpleSchema({
		subProperty : String,
	}))
})

sampleSchema.validate({
	property : {
		subProperty : 'stringy string',
	}
})

sampleSchema.validate({
	property : {
		subProperty : 1,
	}
}) // ClientError: Sub property must be of type String
