When using canonical addressing, these two schemas should behave *exactly* the same. Canonical addressing means that the use of "id" has *no* effect on schema lookup/dereferencing- so *neither* of these examples would have any effect on references to "http://example.com/other-schema#" anywhere else.

example1.schema.json

{
	"title": "Some schema",
	"items": {
		"id": "http://example.com/other-schema",
		"type": "array",
		"items": {"$ref": "#"}
	}
}

example2.schema.json

{
	"title": "Some schema",
	"items": {
		"type": "array",
		"items": {"$ref": "http://example.com/other-schema#"}
	}
}
