Hmmm.  I think one of the keys to the early update of CAP has been  
that simple concepts are represented in simple ways.

Other folks may feel differently, but I'm not certain the EDXL  
routing application really needs the full functionality provided by  
this much bulkier representation.  E.g., in the past we've handled  
included polygons... which much more often involve different  
information or instructions than mere exclusion... by overriding them  
with other blocks referencing other simple polygons.

So it sounds like the TC may need to revisit the question of whether  
we want to follow the GML standards in full, or some other precident,  
or stick to a simplified model.
