DOCBOOK: affiliation changes that were supposed to be in 4.0

The TDG reference page for <affiliation> says

  In DocBook V4.0, Affiliation will be removed from some of the places in 
  which it now occurs. Instead of appearing inside Author, for example, a new 
  wrapper element will be created to hold Author, AuthorBlurb, and 
  Affiliation.

It looks to me like <affiliation> and <authorblurb> are still part of the
content model of <author>. Are there still plans to change this?
