ins and del elementsThe cite attribute may be used to
specify the address of a document that explains the change. When
that document is long, for instance the minutes of a meeting,
authors are encouraged to include a fragment identifier pointing to
the specific part of that document that discusses the change.
If the cite attribute is present, it must be a
valid URL
potentially surrounded by spaces that explains the change.
The datetime attribute may be
used to specify the time and date of the change.
If present, the datetime attribute's value must be a
valid date string with
optional time.
The ins and del elements implement the HTMLModElement interface:
interface HTMLModElement : HTMLElement {
attribute DOMString cite;
attribute DOMString dateTime;
};
