Subject: implementing links between two classes in CLOS (without inheritance)

Hi,

Can anybody help me?

How could I define a specialized Class Metaobject class (as a subclass of  
standard-class) to implement a simple link (i.e. a relationship) between 
classes with the MOP?

In fact, I would like to be able to propagate (in a way similar than inheritance)
an attribute from a class A to another class B ( but A and B are not related
in a inheritance lattice) and read (or compute) this derived attribute from B.

This is not explicitly explained in The Art of MOP.

Thanks
