 There are some implementation details developers must consider:
+
 - JastAdd doesn't support `Map`. So, it must be constructed in a tuple (AST-Node). e.g. `ServerVariablesTuple ::= <Name> S:ServerVariableObject;` <-> `variables` in [Server Object](https://github.com/OAI/OpenAPI-Specification/blob/main/versions/3.0.3.md#serverObject)
+
 - In OAS, several objects can be replaced by [Reference Object](https://github.com/OAI/OpenAPI-Specification/blob/main/versions/3.0.3.md#referenceObject). In `RAGO`, we implemented this structure in an abstract node to every concerned object. e.g. [Parameter Object](https://github.com/OAI/OpenAPI-Specification/blob/main/versions/3.0.3.md#parameterObject) 
   ``` 
   abstract ParameterOb;
   ParameterReference : ParameterOb ::= <Ref> ...;
   ParameterObject : ParameterOb ::= <Name> <In> ...;
   ```
+
 - Most objects can be extended with `Extension` containing unfixed name and values. In JastAdd, this is also implemented in a tuple (AST-Node) `Extension ::= <Key> <Value:Object>;`
