Yes, that's true, but it is reality and it is what browsers must do in 
order to remain compatible with millions of legacy documents.  Keep in 
mind that such requirements would only apply to documents served as 
text/html, not XML.

Authors who check their pages using a conformance checker would be 
alerted to the error.  A typical browser can't do that (at least not by 
default) because the average user just doesn't care or need to know 
about such errors.

There are already tools available for developers that can alert them to 
such errors.  e.g. The error consoles in Firefox, Opera, Safari, iCab, 
etc. and various validator extensions which report markup, CSS and JS
