#332: WKT geometry tag match and mismatch
  Reporter:  mloskot  |       Owner:  pramsey      
      Type:  defect   |      Status:  new          
  Priority:  medium   |   Milestone:  PostGIS 1.5.0
 Component:  postgis  |     Version:  trunk        
Resolution:           |    Keywords:               
Comment (by mloskot):

 The OGC SFS documented in 99-049 does not specify the handling of case of
 WKT grammar elements, so it is not incorrect to assume implementors can
 handle it differently.

 However, more recent implementation specification published as document
 OGC 06-103r3 does specify it precisely in ''7.2.1 BNF Introduction'':

  ''The text representation of the instantiable Geometry Types implemented
 shall conform to this grammar. Well known text is case insensitive. ''

 This suggests that the current inconsistent behaviour might be also
 invalid - it depends if and to which version of OGC specification PostGIS
 claims to conform.
