In the Moodle FileAPI (http://docs.moodle.org/dev/File_API) there is a line of code:
if ($filearea !== 'expectedfilearea' && $filearea !== 'anotherexpectedfilearea') {
I suspect these are not as literal as they appear and they should be substituted. But to what? I can find no additional reference to them. If someone could provide a reference I'd be very grateful.

It is up to your own plugin to decide what to call the filearea(s) that you create.
This is just a check to make sure that the name of the filearea in the URL matches one of the fileareas that you are using.
For example, mod_forum, defines fileareas called 'attachment' (for files attached to a post, via the 'attachment' box) and 'post' (for files embedded within the text editor for the post).
