  Returns AWS resource descriptions for running and deleted stacks. If <code>StackName</code> is specified, all the
  associated resources that are part of the stack are returned. If <code>PhysicalResourceId</code> is specified,
  the associated resources of the stack that the resource belongs to are returned.
  </p>
  <note>
  <p>
  Only the first 100 resources will be returned. If your stack has more resources than this, you should use
  <code>ListStackResources</code> instead.
  </p>
  </note>
  <p>
  For deleted stacks, <code>DescribeStackResources</code> returns resource information for up to 90 days after the
  stack has been deleted.
  </p>
  <p>
  You must specify either <code>StackName</code> or <code>PhysicalResourceId</code>, but not both. In addition, you
  can specify <code>LogicalResourceId</code> to filter the returned result. For more information about resources,
  the <code>LogicalResourceId</code> and <code>PhysicalResourceId</code>, go to the <a
  href="https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/">AWS CloudFormation User Guide</a>.
  </p>
  <note>
  <p>
  A <code>ValidationError</code> is returned if you specify both <code>StackName</code> and
  <code>PhysicalResourceId</code> in the same request.
