 Pseudo Parameters

-In addition to parameters defined by a template author, Heat also creates two
-parameters for every stack that allow referential access to the stack's name
-and identifier. These parameters are named ``OS::stack_name`` for the stack
-name and ``OS::stack_id`` for the stack identifier. These values are accessible
-via the `get_param`_ intrinsic function just like user-defined parameters.
