Digging into some www-style mailing list archives (official ML for discussing 
W3C CSS specification), I found following mail.

I refer mainly to:
"If other browsers pass the entire W3C CSS1 Test suite, then they too could
claim a similar level of conformance."
and
"which was certainly not true for other browsers at the time (among others, 
the section 4.1.4 test [1] was particularly brutal, on even those browsers 
who at the time were claiming "superior conformance/compliance" - the results 
can be seen in Eric Meyer's leader board [2])."

Questions are:
1) is Konqueror/KHTML CSS1 compliant?
  if answer is Yes, I guess we should apply for "conformance"
2) has somebody seen Eric Meyer's leader board [2]?
 (short guess: Konq is not listed there...)

Thanks,

Vadim

P.S. my testing of 'float' shows that Konq has very good support for it. 
Hope, we can pass those test :-)
Also quite interesting results with MS IE6 (which I installed recently)
It, indeed, has very good CSS support in HTML4-Strict.
When Doctype is HTML4-Transitional, it fastly goes into "quirk" mode.
Surprisingly, but it also has bad layout when Doctype is XHTML 1.0-Strict or 
XHTML 1.0-Transitional.
But official position of MS that XHTML is *not supported*, for example, by 
MacIE5. 
As Konq suports XHTML, I think we should place this (XHTML support) in 
Release Notes.  It seems that we easily beat MS here.

I can only assume you are trolling Ian, so I'll bite. ;-)

As measured by the W3C CSS1 Test Suite (the only official valid way to
measure compliance to CSS1 - unless you have a better suggestion),
IE6/Windows has full CSS Level 1 compliance, just as IE5/Mac did when it
shipped over a year ago, which was certainly not true for other browsers at
the time (among others, the section 4.1.4 test [1] was particularly brutal,
on even those browsers who at the time were claiming "superior
conformance/compliance" - the results can be seen in Eric Meyer's leader
board [2]).

If other browsers pass the entire W3C CSS1 Test suite, then they too could
claim a similar level of conformance.

Yes, see above.  IE6/Windows passes the CSS1 Test Suite pages which test
'ex' and 'float'.
