I'm not entirely sure of the relationship in coordinates between the graphic and 
the surface.  Unless the unit of measurement is determined on the surface and 
then all the coords are defaultly in that unit of measurement (and in that case 
it must be a real-world physical unit, i.e. not pixels).

I'm not sure. If the coords is on graphic, in units of measurement referring to 
the surface, then they both cover the same distance.  (One simply does it with 
greater resolution in its reproduction of that surface.) If coords is on a zone, 
then it makes sense that it is in relation to whatever unit of measurement is 
use for the graphic (presumably pixels).

I think then the l/@corresp (or specialised attribute) could point to all three 
zones, and that these zones would have different coords in relationship to the 
graphic which contains them.  However, it is equally possible for there just to 
be a l/@xml:id which then each of the zones point to.  (And in fact, that way 
round of zones pointing to lines stand-offishly rather than the reverse would 
naturally be my preference, I believe.)

I'm still a bit fuzzy on the details of the relationship between surface and 
graphic and would like more clarification from Conal and others how they see 
that working. Maybe the examples being reworked as Conal suggested would help.
