questions about metadata elements

pubMetaElem.dita 
talks about:
author, publisher, copyright

 

mgtMetaElem.dita 
talks about:
source, critdates, permissions, resourceid

 

metaQualElem.dita 
talks about:
audience, category, keywords, prodinfo, othermeta, 
data

 

These are the only 
*Elem.dita topic files. The following are not mentioned in them:

 

metadata, data-about, 
foreign, unknown
linktext, searchtitle, 
shortdesc
authorinformation
navtitle, exportanchors

 

Are they discussed elsewhere in the Architecture Spec? If 
not, should they be treated on a par with the above as metadata elements? Or are 
they set aside for a reason?

topicmeta is the 
union of prolog and metadata, 
plus children of metadata
plus linktext, 
searchtitle, shortdesc, navtitle, exportanchors
(and in bookmap: plus authorinformation as 
alternative to author)

As to including metadata as a peer of its own children, 
isn't backward compatibility wonderful!  !->
