This seems like less than ideal behavior. What is the point of DOCTYPE if
UAs don't make any kind of decisions based upon it?

I think this might be a very good time, then, to propose that the HTML 5
spec state clearly that text/html content should be parsed as HTML 4 unless
there is a valid HTML 5 DOCTYPE within the document (whatever the HTML 5
DOCTYPE is, it seems to change or be under debate). I believe that to free
ourselves of the concerns of backwards compatability, as well as not
accidentally break any pages, would be more than worth it, especially since
all you would be asking UAs to do is have a simple two-way toggle at the
beginning of their parse routines.

Thoughts? Am I off my rocker?
