ERROR DESCRIPTION:                                              
Starting with 6.0.1.4 version of WPS, attributes of the target  
data                                                            
object of a DataMap, cannot be set by making assignments to the 
temp                                                            
variables generated by the map service runtime. This did work in
earlier                                                         
versions of WPS. For example, if data object A has an attribute 
B, then                                                         
a temp variable called A_B is available and attribute B can be  
set by                                                          
making an assignment A_B = <expression>.  But this does not work
in
