Depends on what you want the attributes to "do".  If they are to work
like the attributes in the UML class, you cannot make it with a shape,
but have to do C coding.  You do *not* want to modify the UML Class
shape - it's a horrible hack in many ways.  Adding and removing
connection points is not *too* hard, several nicely-behaving objects do
it.  The text part depends a lot on where it should go, how complex the
text is, and how it should be editable.  We do not yet have a really
good way to handle lists of attributes like in the UML class.
