I stumbled across th message when I watched the StatusCode.csv on github (Se also attached image, or https://github.com/OPCFoundation/UA-Nodeset/blob/044132f275185481c435d0396014e4e9f6836f9e/Schema/StatusCode.csv):
"We can make this file beautiful and searchable if this error is corrected: It looks like row 50 should actually have 3 columns, instead of 4. in line 49. "

The reason is, for example, in the following line, which has a comma in the description text. https://github.com/OPCFoundation/UA-Nodeset/blob/044132f275185481c435d0396014e4e9f6836f9e/Schema/StatusCode.csv#L50

The rfc4180 suggests adding double quotes for these fields.

From: https://tools.ietf.org/html/rfc4180

6.  Fields containing line breaks (CRLF), double quotes, and commas should be enclosed in double-quotes.

So I would suggest adding double quotes to all CSV fields that (can) contain a comma or other special characters.

This change might break some existing parsers of these files, but will improve overall compatibility.

This may also be a problem in other CSV files in the repository.
