    # Removes all block (and optionally span) level HTML tags from the element tree.

    # This converter can be used on parsed HTML documents to get an element tree that will only
    # contain native kramdown elements.
    #
    # *Note* that the returned element tree may not be fully conformant (i.e. the content models of
    # *some elements may be violated)!
    #
    # This converter modifies the given tree in-place and returns it.
