class DomMutation:
    """Represents a DOM mutation event from add_dom_mutation_handler.

    Attributes:
        element_id: The ``data-__webdriver_id`` attribute value set on the
            mutated element by the MutationObserver. Use this to locate the
            element from the main thread if needed.  For ``characterData``
            mutations this identifies the parent element of the text node.
        attribute_name: The name of the changed attribute (``attributes``
            mutations only).
        current_value: The value after the mutation (attribute value or
            character data; ``None`` if the attribute was removed).
        old_value: The value before the mutation.
        type: The mutation type: ``attributes``, ``childList`` or
            ``characterData``.
        target: Same identifier as ``element_id``; named per the
            cross-binding BiDi API design.
        added_nodes: Node descriptors added by a ``childList`` mutation.
            Element descriptors carry ``nodeType``/``nodeName``/``id``
            (a ``data-__webdriver_id`` value); other nodes carry
            ``nodeType``/``nodeName``/``value``.
        removed_nodes: Node descriptors removed by a ``childList`` mutation.
