In previous version there have been the 'server' and 'client' terms 
instead 'host'. However it is obvious for me that there can be as 
servers as clients that do not recognize some headers of another side of 
exchange.

No, that just describes the behavior of the host after receiving the 
H-N-R header. However this paragraph needs improvement, and I'll do that 
in the next version of the draft, which will bw available at the end of 
Last Call.
