Overview

DocumentType (‘<!doctype html>`) — exposes name / publicId / systemId and nodeType=10. HTML5 doctypes carry empty public/system IDs, but `implementation.createDocumentType` can set them.

Constructor Details

#initialize(name, public_id = "", system_id = "", owner_document: nil) ⇒ DocumentType

‘owner_document:` links a live doctype (document.doctype) to its document so the ChildNode methods (remove/before/after/replaceWith) act on the tree; a standalone doctype (DOMImplementation.createDocumentType) has none, so those methods are no-ops per spec.
