I guess I could have stated myself a little clearer.
The spec says:
"DOCTYPEs are required for legacy reasons. When omitted, browsers tend to
use a different rendering mode that is incompatible with some
specifications. Including the DOCTYPE in a document ensures that the browser
makes a best-effort attempt at following the relevant specifications."
My point is, as the only possible use for a DOCTYPE declaration in HTML (any
version) is for including <!ENTITY >declarations, and no browser to my
knowledge does, not even the niche browsers, why bother with an DOCTYPE
declaration at all. As you point out
<tab>Doctypes in HTML have never, in practice, actually done anything
Surely the Living HTML Spec could be cutting out some dead-wood here.
(Perhaps it's here just as some 'sacred cow' talisman and to prevent some
'hurt feelings' :>)
