 Reporter:  pramsey      |       Owner:  pramsey      
     Type:  enhancement  |      Status:  new          
 Priority:  medium       |   Milestone:  PostGIS 2.1.0
Component:  postgis      |     Version:  trunk        
 Keywords:  sql/mm       |  
-------------------------+--------------------------------------------------
 In general, GML allows representation of curved features from SQL/MM so we
 should be able to consume them.

 For example:
