This is an archived snapshot of W3C's public bugzilla bug tracker, decommissioned in April 2019. Please see the home page for more details.
In Section 8.1.1[1], the current published specification says: > A DOCTYPE is a mostly useless, but required, header. It then goes on to say: > DOCTYPEs are required for legacy reasons. When omitted, browsers tend to use a different rendering mode that is incompatible with some specifications. So, not useless then, or even mostly useless, as it's required to ensure that the most common UAs in the world (web browsers) behave something close to properly. Perhaps consider dropping the "mostly useless" comment to avoid encouraging skimmers to drop it. Perhaps "A DOCTYPE is a required header that primarily serves a legacy, but significant, purpose." (Separately: It's a header? That seems an odd term for it.) [1] http://www.w3.org/TR/html5/syntax.html#the-doctype
See ISSUE-4 (http://www.w3.org/html/wg/tracker/issues/4), ACTION-93 http://www.w3.org/html/wg/tracker/actions/93 and the corresponding Change Proposal http://lists.w3.org/Archives/Public/public-html/2010Jan/0015.html and point 7 of the rationale thereof.
The change Larry Masinter referenced would fix this issue if committed. I'm glad to see that change avoids using "of limited utility" as well, since that has many of the same problems as "mostly useless" (other than the latter's problem of tone).

Checked in as WHATWG revision r4940. Check-in comment: I guess useless is the wrong word, so commenting it out until I work out what the right word is... http://html5.org/tools/web-apps-tracker?from=4939&to=4940
