I was actually thinking about this the other day...  We could add a new 
pseudo-class for matching form controls that have their default value 
(or that don't, depending on how we expect this to be used).  then you 
could style :invalid:not(:has-default-value) specially, say....

Or I suppose we could just add a new pseudo-class that means the above.

Are there cases when pages would set invalid default values and want 
them flagged as such in UI?
