Extension of UML/UML - Class possible?

[Erik Wasser <erik wasser iquer net>]

Is it possible to extend the "UML - Class" object of an additional field 
for a comment? I don't know, if this is conform the UML standard, but I 
think it would be very handy. Something like this:

+-------------------+
| classname         |
+-------------------+
| Attributes        |
+-------------------+
| Methods           |
+-------------------+
| Comment           |
+-------------------+

Is it possible?

Thx for your help & work.
