We also need to ensure that authors receive guidance about the problems that dialog / application mode, can cause for some AT users.  The keyboard interaction of AT that switches into application mode changes significantly if the <dialog> element does not have a child element with role="document".

Sometimes it will be desirable to provide a true dialog (Yes, No, Cancel), other times authors should be nesting a container with role="document" within the dialog, to retain the expected keyboard interaction.

IMO, it is desirable to have the focus return to the element which caused the dialog to open.

It is also important that the content available to screen-readers be restricted to the dialog's contents.  As screen-reader users usually lack access to the visual affordances to separate dialog contents from the background.
