None


.. _semrole-column-horz-dep:

3.28.5. Horizontal Dependencies
-------------------------------

Sem_Role is dependent on the :ref:`G_Type Column <gtype-column-dep-by>`.

If the corresponding G_Type code is ``C``, ``FA``, or ``G``, the Sem_Role code
must be ``X``.  Otherwise, anything that is appropriate for the current 
utterance is allowed.
