@ -1215,11 +1215,10 @@ Each ``material`` element can have the following attributes or sub-elements:
An element with attributes/sub-elements called ``value`` and ``units``. The
``value`` attribute is the numeric value of the density while the ``units``
can be "g/cm3", "kg/m3", "atom/b-cm", "atom/cm3", or "sum". The "sum" unit
indicates that values appearing in ``ao`` attributes for ``<nuclide>`` and
``<element>`` sub-elements are to be interpreted as nuclide/element
densities in atom/b-cm, and the total density of the material is taken as
the sum of all nuclides/elements. The "sum" option cannot be used in
conjunction with weight percents. The "macro" unit is used with
indicates that values appearing in ``ao`` or ``wo`` attributes for ``<nuclide>``
and ``<element>`` sub-elements are to be interpreted as absolute nuclide/element
densities in atom/b-cm or g/cm3, and the total density of the material is
taken as the sum of all nuclides/elements. The "macro" unit is used with
a ``macroscopic`` quantity to indicate that the density is already included
in the library and thus not needed here. However, if a value is provided
for the ``value``, then this is treated as a number density multiplier on
