Work is underway for richer ways to express meta-data. INS and DEL
therefore don't provide extensive means to represent previous
versions etc. The id, cite, datetime and title attributes should
be sufficient. ID can be used by meta-data to name the INS or DEL
element, CITE allows you to point to such meta data or an informal
description for the reason for the change, previous version, who
made the change etc. DATETIME was a recent addition which can be
used to highlight changes since a given date etc. TITLE can be
used to include an informal note describing the change in place
in the html document.
