To begin, escuse my language, I'm a french guy ...

Is it possible to do an assiocation between an attribute of class 'A' and an attribute of class 'B' which not a primary key ?

If is possible, How ??

Thanks for response.

Well, I'm not sure I understood what you want... Though I'm french too :-).

What type of association is there between your A and your B, and more important : which multiplicity (cardinalité, multiplicité, quoi) is there between those ?

Romain007: look for property-ref attribute in the documentation. It applies to <many-to-one> and <one-to-one>.
