Displays the transaction records of the specified element
    generation and all of its ancestors. The transaction records are
    listed in reverse chronological order. If you do not specify a
    particular generation, the list begins with the latest generation
    on the main line of descent.

    The ancestors of a main line generation are all the preceding
    generations back to the first generation of an element. The
    ancestors of a variant-line generation are all preceding
    generations on the variant line of descent, and any generations
    back to the first generation on the main line.
