Re: Rough cut Fe25 CSVW minutes

A couple of comments on topics discuss in today's meeting:
>> http://www.w3.org/2015/02/25-csvw-minutes.html

1. Re union datatypes.   I am wary of endorsing union datatypes.  Doing 
so would add complexity that IMO would be detrimental.   By creating 
this W3C Recommendation, this working group has an opportunity to 
recommend good ways to make spreadsheet data most readily machine 
interpretable, and I don't think unions are a good practice.  If they 
are permitted I think they should at least be marked as not recommended.

2. Re multiple null values.   Please do not endorse the notion of 
multiple null values.  I can see Jeremy's reason for doing it, but it is 
really combining two pieces of information into a single field: null + 
reason.   It is no longer just null (no data).  If someone wants to have 
multiple null values, then they can use a separate user-defined datatype 
for that.

Thanks,
David Booth
