I think you are forgetting, Ivan, that this IS an XHTML 2 working group 
document.  The list in the document is the definitive list from the 
XHTML 2 Working Group.  We are not planning to change it.  If there are 
items missing, those will surface during last call and we should add 
them.  Once that is done, the list is done.
