Morning Maik,

When I first saw this I thought Agh! OK, I'll fix the error in the 
Editors draft for next time. However, reading through the example more 
carefully I think the error is deeper than that. It's a set of CSV files 
that are described by json files - but this isn't clear and I think 
you're right that it needs fixing. Ironic (I mean bad) that we made this 
mistake in a document published on the same day as the CSV work on which 
the example is based made it to Rec!

I've raised this issue. The editors will get back to you when it's fixed.


Tracker: Issue-232
