You're almost on the right place, this is the list of developer
discussions. There is a xmlBlaster list (without devel) where users
messages (like yours) will be exchanged.
Just subscribe as you did for the devel list.

For my understanding, once a message has been published, it's published
with the given key.
You may erase it, or publish the same content with another key or change
the mime types.

It stops the xmlBlaster notifying you about privious subscribed messages,
subscribed either per oid or per XPath.
If you subscribe again, the behavior depends on some qos settings.
Take a look at the demo/HelloWorld clients and play with them to see how
It's real fun!
