Error in the example 21 of Typed Values

Hi all,

 

I had a look at the examples of Typed Values
https://www.w3.org/TR/json-ld/#typed-values

and got confused by Example 21 vs Example 23

 

The narrative below Example 23 explains:

As a general rule, when @value and @type are used in the same JSON object,
the @type keyword is expressing a value type. Otherwise {if @id is present
in the object}, the @type keyword is expressing a node type.

 

Sections 8.2 and 8.3 of the specification support that view at a formal
level.

 

The JSON-LD code of example 23 and the comments in grey align to that.

 

But Example 21 shows as code

"modified":

    {

      "@id": "http://purl.org/dc/terms/modified",

      "@type": "http://www.w3.org/2001/XMLSchema#dateTime"

    }

and explains by a table below it that a JSON-LD processor will interpret
this code as @type defines the type of the value of modified.

This is a clear contradiction to the explanation below Example 23.

 

 

Please clarify if my view is wrong or if example 21 has an error.

 

Thanks,

Michael
