---------------------------------------

Well missing periods are embarrassing, sorry about that. Thanks for being 
nit-picky.

What are you using to view ascii docs? I'm using a plugin for intellij but I 
don't think the links between documents work in it (I changed it to flowfile 
and still doesn't work).

I got "flow" when I tried to figure out the link from the developer's guide 
online. I think I didn't wait long enough for the url to fully expand.

> The expression language guide should talk about standard flowfile attributes

> The expression language should include a paragraph talking about standard 
> flowfile attributes.  There really are very few besides say filename, path, 
> uuid.  But these should be talked about.  And the fact that this is about it 
> is also good to point out.  It would also be be beneficial to describe how a 
> user can see what attributes were on a flowfile at a given point in the flow 
> to aid the user in debugging and truly understanding the flow.
