That's one of the questions I had on the 'Merging Branch_Stable and Branch_CP as a single branch..." thread.
The documentation on JBoss5 could for instance reflect things that are specific to JBoss5 (For instance the ChannelFactory for JGroups can only be used on JBoss5, the properties for the new binding-manager, the SecurityMetaDataStore on JBoss5).
I think we should reformulate the documentation a little bit to be version independent. Maybe adding a chapter "JBoss5 specific"/ "JBoss4 specific"/EAP Specific.. I don't know... something along that line.
We still have also the versions written on the doc, the remoting version required on EAP/JBoss.. and some other things.
You didn't answer the question, where the current documentation you put in Branch_1_4 came from?
That's the documentation from Branch_Stable, intended for JBoss5.
I was just saying that merging those docs will require some writing to adjust the text.
