docDate has as much right to existence as the other doc* things I think. 
But yes, both it and change should take a  @when  (I won't argue for a 
@period)

While we're wreaking havoc with existing documents, it occurred to me 
this morning that there was no other good reason why we shouldn't rename 
@notBefore as @after and @notAfter as @before.
