A comment example

• A heavily-commented Attr class:

    class Attr
    {
       /** The attribute name. */
       private String name;
  
       /** The attribute value. */
       private Object value = null;
  
      /**
       * Creates a new attribute.
       * @see Attr2
       */
       public Attr (String name)
       {
          this.name = name;
       }
    }
