Your assumption seems to be that the interoperable handling of HTML
documents is to somehow abort processing. This is not the case. Each error
has explicitly defined error-recovery behaviour. The user need never know
there was an error. The error-recovery behaviour described in HTML5 is as
close to what IE does today as humanly possible.
