Re: [Cppcms-users] Small issues in cppcms 1.x.x

Hello Artyom,

The RFC says:

        A JSON text is a serialized object or array.
        
              JSON-text = object / array

Then, you are right, JSON-text is an Object or Array only.

But, the RFC says about Values:

        2.1.  Values
        
           A JSON value MUST be an object, array, number, or string, or one of
           the following three literal names:
        
              false null true

Therefore the string "Hello World" is a valid Json Value syntax. I think
that the cppcms::json::value parser should accept a valid Json Value
syntax.

If you had a class "cppcms::json::json_text" or similar, the parser of
this type should only accept Object or Array syntax. As you have pointed
out.

Daniel.
