Capability EXPRESS information model
This section describes the EXPRESS information model for the capability.

GYL-7 by Leif Gyllstrom (2005-11-09) [minor_technical, open] - {Type = usage}
In the examples given the State_definition representing the state is
classified as State_of_environment. This is missleading since the State_definition
is not defining the state of the environment but the environment itself.
If Environment_typical would have been a subclass od State_definition in the
ARM it would probably have been namned Environment_typical. Therefore
I would suggest to create a subclass to State_definition in the RDL named
"Environment_typical"

GYL-6 by Leif Gyllstrom (2004-03-06) [minor_technical, closed] - {Type = usage}
Should the state_definition module really be part of the
usage section since it's being brought in by the
representing_state_type capability ?
Comment:
(Rob Bodington 04-05-07)
The capability is no longer dependent on representing_state_type capability
As all that is required from the state_definition module is
state_definition.
It makes no sense to typical environments. Any environment can follow on
from any other environment.

Applied_state_definition_assignment
An Applied_state_definition_assignment is a mechanism that
enables an object to have or to be in a State_definition.
ENTITY Applied_state_definition_assignment;
described_state_definition : State_definition;
assigned_to : state_definition_of_item;
role : State_definition_role;
END_ENTITY;
described_state_definition:
the State_definition that is assigned.
assigned_to:
the object whose State_definition is given by the
described_state_definition.
role:
the purpose of the association of the Applied_state_definition_assignment with product or activity data.
State_definition
A State_definition is a mode of being.
A State_definition defines the types of State that can exist.
A State's existence can be assessed and asserted against
State_definition from State.
ENTITY State_definition;
name : STRING;
description :
OPTIONAL
STRING;
END_ENTITY;
name:
the words by which the State_definition is known.
description:
the text that provides further information about the State_definition. The value of this attribute need not be specified.
