This (and the tests in git,
https://github.com/w3c/csvw/tree/gh-pages/syntax  ) are great.

Slight aside but, ...

I was thinking of ways in which we might express tests against CSV
files. Would this kind of structure make sense?:

For each CSVish file, e.g.

Have a corresponding tests directory, e.g. test-utf8-expected/

and then within that, one file per cell, so filenames and contents
something like this:

cell_labels_2.txt: test number

cell_0_0.txt: Я могу есть стекло, оно мне не вредит.

cell_1_2.txt: 2014-02-11

cell_2_0.txt: ""never again""

we said

In other words, the bytes (assumed utf-8?) in each text file would
correspond to cell values indicated in the filename. An alternative
would be to have some other canonically easy to parse tabular data
notation (such as how we used ntriples in the old RDF WG).

We could then use different CSV parsers and check whether the expected
contents match the parsed results.
