<p>
Indicates whether CloudFormation can determine the target value, and whether the target value will change before
you execute a change set.
</p>
<p>
For <code>Static</code> evaluations, CloudFormation can determine that the target value will change, and its
value. For example, if you directly modify the <code>InstanceType</code> property of an EC2 instance,
CloudFormation knows that this property value will change, and its value, so this is a <code>Static</code>
evaluation.
</p>
<p>
For <code>Dynamic</code> evaluations, can't determine the target value because it depends on the result of an
intrinsic function, such as a <code>Ref</code> or <code>Fn::GetAtt</code> intrinsic function, when the stack is
updated. For example, if your template includes a reference to a resource that's conditionally recreated, the
value of the reference (the physical ID of the resource) might change, depending on if the resource is recreated.
If the resource is recreated, it will have a new physical ID, so all references to that resource will also be
updated.
