  * <p>
  * Applications that use Robot for purposes other than self-testing should
  * handle these error conditions gracefully.
+ * <p>
+ * Platforms and desktop environments may impose restrictions or limitations
+ * on the access required to implement all functionality in the Robot class.
+ * For example:
+ * <ul>
+ * <li> preventing access to the contents of any part of a desktop
+ * or Window on the desktop that is not owned by the running application.</li>
+ * <li> treating window decorations as non-owned content.</li>
+ * <li> ignoring or limiting specific requests to manipulate windows.</li>
+ * <li> ignoring or limiting specific requests for Robot generated (synthesized)
+ * events related to keyboard and mouse etc.</li>
+ * <li> requiring specific or global permissions to any access to window
+ * contents, even application owned content,or to perform even limited
+ * synthesizing of events.</li>
+ * </ul>
+ *
+ * The Robot API specification requires that approvals for these be granted
+ * for full operation.
+ * If they are not granted, the API will be degraded as discussed here.
+ * Relevant specific API methods may document more specific limitations
+ * and requirements.
+ * Depending on the policies of the desktop environment,
+ * the approvals mentioned above may:
+ * <ul>
+ * <li>be required every time</li>
+ * <li>or persistent for the lifetime of an application,</li>
+ * <li>or persistent across multiple user desktop sessions</li>
+ * <li>be fine-grained permissions</li>
+ * <li>be associated with a specific binary application,
+ * or a class of binary applications.</li>
+ * </ul>
+ *
+ * When such approvals need to given interactively, it may impede the normal
+ * operation of the application until approved, and if approval is denied
+ * or not possible, or cannot be made persistent then it will degrade
+ * the functionality of this class and in turn any part of the operation
+ * of the application which is dependent on it.
