@Crissov It's the attribute in the current DOM, which can come from original HTML source or set in JS. But e.g. if you change the [`value` IDL attribute](https://html.spec.whatwg.org/multipage/input.html#dom-input-value) of an `<input>` element, the [`value` DOM attribute](https://html.spec.whatwg.org/multipage/input.html#attr-input-value) will not reflect that change (it would for the [`defaultValue` IDL attribute](https://html.spec.whatwg.org/multipage/input.html#dom-input-defaultvalue)).
