[kde-doc-english] question on <author> in <chapterinfo>

[Jack]

Good morning,

I'm working on the docs for KMyMoney, and am converting the author  
information to entities.

In index.docbook, everything matches what I find as examples in  
template.docboook.

However, in many of the chapters, I'm finding
  <author><firstname>A</firstname><surname>B</surname>
           
<affiliation><address><email>ab at c.org</email></address></affiliation>
  </author>

Is the use of the affiliation and address tags correct here?  Should I  
leave or remove them?

Thanks for any advice, suggestions, or pointers to the appropriate doc  
I missed reading.

Jack
