10. This implementation will not implement the `NodeIterator` and `TreeWalker` APIs. They are horribly conceived and impractical APIs that few people actually use because it's literally easier and faster to write recursive loops to walk through the DOM than it is to use those APIs. Walking downward through the tree has been replaced with the `ParentNode::walk` generator, and walking through adjacent children and moonwalking up the DOM tree can be accomplished through simple while or do/while loops.
11. All of the `Range` APIs will also not be implemented due to the sheer complexity of creating them in userland and how it adds undue difficulty to node manipulation in the "core" DOM. Numerous operations reference in excrutiating detail what to do with Ranges when manipulating nodes and would have to be added here to be compliant or mostly so -- slowing everything else down in the process on an already extremely front-heavy library.
12. The `DOMParser` and `XMLSerializer` APIs will not be implemented because they are ridiculous and limited in their scope. For instance, `DOMParser::parseFromString` won't set a document's character set to anything but UTF-8. This library needs to be able to print to other encodings due to the nature of how it is used. `Document::__construct` will accept optional `$source` and `$charset` arguments, and there are both `Document::load` and `Document::loadFile` methods for loading DOM from a string or a file respectively.
13. Aside from `HTMLElement`, `HTMLTemplateElement`, `MathMLElement`, and `SVGElement` none of the specific derived element classes (such as `HTMLAnchorElement` or `SVGSVGElement`) are implemented. The focus on this library will be on the core DOM before moving onto those. They may or may not be implemented in the future.
13. Aside from `HTMLElement`, `HTMLPreElement`, `HTMLTemplateElement`, `HTMLUnknownElement`, `MathMLElement`, and `SVGElement` none of the specific derived element classes (such as `HTMLAnchorElement` or `SVGSVGElement`) are implemented. The ones listed before are required for the element interface algorithm. The focus on this library will be on the core DOM before moving onto those -- if ever.
