Please humor my ignorance and explain how a subject line (which is 
(over)signed) can be dealt with in the current DKIM spec?

I get how footers can be dealt with, read appended.  At least as long as 
DKIM only signs a given amount of the (original) body.  (Though HTML 
(read: MIME structures) can complicate this.)  -  Or are you referring 
to something else?
