-**Directive** ([**Text**][text]) represents an instruction
-(declaration or processing instruction).
+**Doctype** ([**Node**][node]) defines the type of the document.
 
 ```idl
-interface Directive <: Text {
-  type: "directive";
+interface Doctype <: Node {

   name: string;
+  public: string?;
+  system: string?;
 }

 ```html
-<!doctype html>
