'Primary' field is boolean, but example is YES

[GoogleCodeExporter]

The Primary field is listed as being a boolean entry, but is shown in the 
example as:- 

Primary : YES
this should be
Primary : true
OR
Primary : "YES" 

I prefer the proper JSON boolean type.
What works/is implemented by clients at present?
