Other information

This spec adds a dialogmodaltarget attribute to button elements. Similar to popovertarget, dialogmodaltarget takes an IDREF and calls showModal() or close() on the idref element, when the button is clicked. It also specifies the reflected dialogModalTargetElement attribute (which allows for cross-root assignment).

As explained in the spec issue, we think some more generic approach would be better for this use case.
