ACK, it does work, for example, in Chromium 21 in document.compatMode === 
"CSS1Compat" (Standards Compliance Mode).  One should get rid of it (or at 
least does not prefer the corresponding branch) anyway.  One, it is 
comparably inefficient; two, it is comparably error-prone; three, it is 
*proprietary*.

ACK.  It is primarily the undocumented, or poorly documented, uncertainties 
of the different Quirks/Compatibility Modes of different browsers and 
versions that bite you later, particulary with client-side DOM scripting.  
What is working today may very well break tomorrow.  Not so with Web 
standards (of whatever flavor), as today's browser vendors do strive to make 
their software *more* standards-compliant.
