Need for ejb-link

If I need to refer an enterprise bean from another, I can use the ejb-ref element. Within this element I specify the home and remote interfaces of the target bean. Now I can do a JNDI lookup of the target bean uing the ejb-ref-name.
Now my doubt is what is the benefit of the optional ejb-link element ? What additional purpose does it serve ?

Howdy, or application assembly, ejb-link can be used when you are referring to another bean within the same .ear file. But it's optional... so why use it?
A couple of reasons;
* It allows the container to (potentially) do some optimizations.
* More importantly, it allows you to have two or more beans with the same <ejb-name> in the same .ear file, and distinguish between them (see page 420 in the spec, for an example).
