That's not true. A typical browser absolutely can and certainly should 
alert users to bugs in the pages, and the TAG finding I cited explains 
why and how. Optional recourse to external validators is not sufficient, 
as the current state of the web proves. *Silent* error recovery from 
incorrect metadata is potentially dangerous. It is rightly discouraged.
