Sorry for reviving this one more time.

In Opera 9.5 HTML 4.0 Transitional and Frameset doctypes with system 
identifier also triggers Almost Standards Mode.

If the Opera team could share their experience with this implementation, 
do you think the change could be made in HTML 5 as well?

One of my concerns is the confusion this inconsistency causes for 
authors and beginners. HTML 4.0 doctypes are often used before all the 
consequences of the doctype switch are fully understood.

Also, my own tests of about 100 websites using the doctypes in question 
(taken from the list created by Philip Taylor) showed me, that those 
sites won't be broken (only slightly in rare cases) if rendered in 
Almost Standards Mode.
Actually, since non-IE browser's Quirks Modes are more standards aware 
than IE's quirks mode, they already look as "broken" as they are in 
IE8's standards mode.

So, imho, users wouldn't be influenced in their experience of the web. 
According to the Design Principles this makes the way free to consider 
authors over users.

Kind regards, ds
