    The following table provides a few concrete examples of standard names and how they are constructed
    with respect to the guideline template.

    Note that "transformations" are a special case, where multiple transformations may be applied,
    and multiple quantities may be compared, operated on, etc. For transformations involving
    multiple quantities (e.g. ``ratio_of_X_to_Y``; see the `section on Transformations <#transformations>`_
    for more information), the above formula may be extended around multiple base names.

    In the latter example, ``ln`` is operating on the quantity ``water_vapor_partial_pressure_assuming_saturation``,
    while ``derivative_of`` is a combined transformation of ``water_vapor_partial_pressure_assuming_saturation``
