OptionalAttribute

All Implemented Interfaces:
```
public class OptionalAttribute
extends Attribute
                    
```
This class is used for representing attributes not explicitly supported by the stack. Such attributes will generally be kept in binary form and won't be subdued to any processing by the stack. One could use this class for both dealing with attributes in received messages, and generating messages containing attributes not explicitly supported by the stack.
