-------------------------------------
Thanks for reviewing Mike!
No I didn't perf the perf task change.. :-) I will look at this again.
Nice catch about the feild name.
As for putting the field names in the file - let's see how this would work - we
need a matching pair: LineDocWriter and LineDocSource, both should expect the
same fields in same order, and, in addition, DocData has some fixed field
names: ID, Body, Name, Date, Title, and a flexible Properties which can include
anything else. If we move to put the field names in the header line as you
suggest, that would make a single line-doc-source for any lineDocWriter which
is nice, But that would require to modify DocData so that all fields - except
for ID which would become mandatory - would be maintained in props. I like it,
except perhaps for performance... what do you think? Is this what you have in
mind?
