So, you expect that in most cases the retries for a reliable channel 
will spread over 30 seconds, and if still unsuccessful, the Association 
and all its channels will be aborted.
Can you explain how you got that 30 seconds figure?

I am not out for requiring improvements and tricks. I just think that 
there should be a sufficient level of descriptions in the specs so that 
designers know what factors they can design with.

For example, in order to tell how many retries or how long period to 
allow for the unreliable channels, it is of interest what values will be 
used for the reliable channels. Approximately.
