    """Edit the attributes of a product

    All IFC entities have attributes. Normally they can be edited directly,
    by simply assigning a new value to them. In some scenarios, you may wish
    to also ensure that ownership history is updated. This function provides
    that convenience.

    :param product: The product you want to edit. This may be any rooted IFC
        entity.
    :type product: ifcopenshell.entity_instance
    :param attributes: a dictionary of attribute names and values.
    :type attributes: dict
    :return: None
    :rtype: None
