Nice work on the refactor and documentation! I think this will meet the 
goal of decoupling from Spring where possible while maintaining a 
natural style in flow XML configuration. I do think there's a lingering 
question of naming/style to discuss and resolve. I think lowercase bean 
names and event ids are standard convention and I can't imagine any 
reason to depart from it. (I fully admit there may be an existing style 
guide for this that I'm not aware of.) In any case it seems worthy of 
discussion before writing much more code/configuration.
