$ref siblings

[rgusmero]

Please consider the following code:

@dataclass
class B:
    id: str

@dataclass
class A:
    x: list[Annotated[B,'desc']]

schema = dataglasses.to_json_schema(A)
pprint.pprint(schema)

The produced output is

{'$defs': {'A': {'properties': {'x': {'items': {'$ref': '#/$defs/B',
                                                'description': 'desc'},
                                      'type': 'array'}},
                 'required': ['x'],
                 'type': 'object'},
           'B': {'properties': {'id': {'type': 'string'}},
                 'required': ['id'],
                 'type': 'object'}},
 '$ref': '#/$defs/A',
 '$schema': 'https://json-schema.org/draft/2020-12/schema'}

AFAIK, though, siblings of $ref are ignored.
