*/
/**
* Core class used by the HTML API to represent a DOCTYPE declaration.
*
* This class parses DOCTYPE tokens for the full parser in the HTML Processor.
* Most code interacting with HTML won't need to parse DOCTYPE declarations;
* the HTML Processor is one exception. Consult the HTML Processor for proper
* parsing of an HTML document.
*
* A DOCTYPE declaration may indicate its document compatibility mode, which impacts
* the structure of the following HTML as well as the behavior of CSS class selectors.
* There are three possible modes:
*
* - "no-quirks" and "limited-quirks" modes (also called "standards mode").
* - "quirks" mode.
*
* These modes mostly determine whether CSS class name selectors match values in the
* HTML `class` attribute in an ASCII-case-insensitive way (quirks mode), or whether
* they match only when byte-for-byte identical (no-quirks mode).
*
* All HTML documents should start with the standard HTML5 DOCTYPE: `<!DOCTYPE html>`.
*
* > DOCTYPEs are required for legacy reasons. When omitted, browsers tend to use a different
* > rendering mode that is incompatible with some specifications. Including the DOCTYPE in a
* > document ensures that the browser makes a best-effort attempt at following the
* > relevant specifications.
*
* @see https://html.spec.whatwg.org/#the-doctype
*
* DOCTYPE declarations comprise four properties: a name, public identifier, system identifier,
* and an indication of which document compatability mode they would imply if an HTML parser
* hadn't already determined it from other information.
*
* @see https://html.spec.whatwg.org/#the-initial-insertion-mode
*
* Historically, the DOCTYPE declaration was used in SGML documents to instruct a parser how
* to interpret the various tags and entities within a document. Its role in HTML diverged
* from how it was used in SGML and no meaning should be back-read into HTML based on how it
* is used in SGML, XML, or XHTML documents.
*
* @see https://www.iso.org/standard/16387.html
