   Priority:  critical      |   Milestone:  3.3.0    
  Component:  SHP Provider  |     Version:  3.2.0

 The SHP header contains the values for the bounding box, including minZ
 and maxZ.
 When these values are not specified some very large double values are
 used. Eliminate the validation of these values since:
 a) such value is not standard
 b) the Z bounding box values are not used.
