Dear Carlos,
You should have a look at the wildcard subscriptions:
http://activemq.apache.org/wildcards.html
<http://activemq.apache.org/wildcards.html>It's more the other way around
though: you publish to a specific topic and all the parent's subscribers
will receive it, instead of publishing to a parent and all the child
subscribers will receive it.

In your example, you could have:
Car.Japanese.Nissan
Car.Japanese.Mazda
Car.American.Ford
Car.American.Chrysler

if you publish to Nissan, subscribers to Car.> or Car.Japanese.> or
Car.Japanese.Nissan or Car.*.Nissan will receive the message.
It's not exactly what you are asking for, but you will obtain the same
results.

Hope it helps!
