Does 'ignoring' mean "treat as if they were not there" or "do not
interpret as tags"? My guess is the former. The latter has the advantage
that useful information can be still presented to the user -- for
example, if my document uses some semantic tagging which a particularly
dim browser doesn't know about. 

Both options  will of course deeply confuse browsers trying to
calculate byte offsets within a file.
