How about: Legacy families have special ways of expressing arrays. ``sub-type`` can be used to define the type of array members in case array members are not fully defined as attributes (in a bona fide attribute space). For instance a C array of u32 values can be specified with ``type: binary`` and ``sub-type: u32``. Binary types and legacy array formats are described in more detail in :doc:`genetlink-legacy`.
