From the spec:

If the KeepAliveTime is set on a WriterGroup, a value slightly higher than the configured value of the group should be used as idle timeout of the connection ensuring that the connection is disconnected if the keep alive message was not sent by any writer. ....

Issue:

It must be explained what the connection means. The AMQP defines connection for:

• Containers,
• session
• Link.

Additionally, it must be explained how this parameter affects the Publisher/Subscribers interoperability. It seems that it is only a parameter of the AMQP Container to Container interoperability.

Anyway, it requires the 1:1 relationship between PubSub WriterGroup and AMQP Container/session/Link (depending on the decision related to the defined above issue) but this relation is not defined or I cannot find any information about it in the AMQP mapping stuff.
