// HTMLMediaElement's instance to use the MSE API (also known as "attaching MSE
// to a media element") by using a Media Source object URL as the media
// element's src attribute or the src attribute of a <source> inside the media
// element, or by using a MediaSourceHandle for a worker-owned MediaSource as
// the srcObject of the media element. A MediaSourceAttachmentSupplement
// encapsulates the linkage of that object URL or handle to a MediaSource
// instance, and allows communication between the media element and the MSE API.
