Having seen what docbook stuff uses, I steal those ideas.
E.g. a chapter on subject pages,
<chapter id='pgs'>
   then

  <example id='pgs.ex.1'>

etc, 

so the names relate to the subject?

I will wait for someone else to answer that one!
I have tried olink, but not include.

Yes, at parse time.

No. Its an error if the id does not exist at parse time.

Perhaps olink would help.
