.. warning::
The concept of a steady state is ambiguous in a perfect foresight
context with permament and potentially anticipated shocks occuring.
Dynare will use the contents of ``oo_.steady_state`` as its reference
for calls to the ``STEADY_STATE()``-operator. In the presence of
``endval``, this implies that the terminal state provided by the
user is used. This may be a steady state computed by Dynare (if ``endval``
is followed by ``steady``) or simply the terminal state provided by the
user (if ``endval`` is not followed by ``steady``). Put differently,
Dynare will not automatically compute the steady state conditional on
the specificed value of the exogenous variables in the respective periods.
