Hello everybody,
     reading the manual (Release 8.2.10), I wonder if the syntax of 
":session" header may not be changed in the way of  ":tangle" or 
":noweb" (sorry for the frenchy expression). I mean :

  * :session yes (now :session)
  * :session no  (now :session none)
  * :session name (now :session name)

It seems to be more homogeneous.

PS: Of course the old syntax must be supported.
