== Link: HTML Doctype declarations inventoried

[[Activating the Right Layout Mode Using the Doctype Declaration
http://hsivonen.iki.fi/doctype/]] is pretty much summarized by its
title. As a bonus, it includes a handy chart of how various browsers
react to various specific DOCTYPE declarations (or did, as of when the
chart was made; browser DOCTYPE behavior is an ever-changing target, and
the chart is a good illustration of how much variety there can be).
