    Parameters
    ----------
    serialized : object
        The serialized form of the association.

    format : str or None
        The format to force. If None, try all available.

    validate : bool
        Validate against the class' defined schema, if any.

    first : bool
        A serialization potentially matches many rules.
        Only return the first succesful load.

    registry : AssociationRegistry or None
        The `AssociationRegistry` to use.
        If None, no registry is used.
        Can be passed just a registry class instead of instance.

    kwargs : dict
        Other arguments to pass to the `load` methods defined
        in the `Association.IORegistry`

    Returns
    -------
    The Association object

    Raises
    ------
    AssociationNotValidError
        Cannot create or validate the association.

    Notes
    -----
    The `serialized` object can be in any format
    supported by the registered I/O routines. For example, for
    `json` and `yaml` formats, the input can be either a string or
    a file object containing the string.

    If no registry is specified, the default `Association.load`
    method is used.
