Andy;

I've updated the R-TableNormalization <http://w3c.github.io/csvw/use-cases-and-requirements/#R-TableNormalization> requirement to reflect your comments ... definitely _not_ intended in the specific RDBMS context!

I've also moved this req to the "deferred" section, as transforming a "normalized" data file to a regular tabular data file would require some generalised parsing. Easy for a programmer to knock something up, difficult for us to anticipate within a specification! So I think this requirement is out of our scope.
