Ambiguity of values

There can be ambiguities when passing a JSON object as a value for a property. Normally, a value as an object is used as a command (to manipulate multiple links, string functions) or possibly for JSON property assignment. It is the command mode that is preferred. As long as the object does not look like a command (and the type of the property does not induce ambiguity), it is considered as any value (so not a command), but if it is necessary to pass a value that could be considered as a command, we can pass the JSON in an object that has a property of name $jsonval.

This is a command, to replace ids in a property multiple :

"property": { 
   "$values": [3, 4, 5],
   "$mode": "replace"
}

This is a value:

"property": { 
  "$jsonval": {
    "$values": [3, 4, 5],
    "$mode": "replace"
  }  
}
