I was listing the three ways that it seemed the spec would allow based 
on current list thinking.  I was objecting to there being three ways.

I agree with combining 1 & 2, and eliminating "max-age" -- it is 
completely redundant.

That would also get rid of any ciunter=intuitive "Expires: <yesterday>" 
distinguished value.
