OK, was my reading too.

That had already come up. However, the object numbers for broken lines, 
etc., are only available at shipout. That makes things challenging, I 

What I'm not clear on is whether one needs all of the object numbers. 
For example, if one creates a link that breaks over a line, each object 
contains the full target data. So for doing e.g. tagging it seems to me 
that one doesn't need 'all the detail'
