Sorry I forgot one more comment:

Can you improve the comments in the following RFC example?


{{{
   # Use the what the layer defines as the projection definition.
   # This may not be available for all data sources or layer types
   # (shapefile, SDE, OGR, etc.).
   PROJECTION
       AUTO
   END
}}}

I don't understand the comment there so it is hard to know what is 
happening.

Thanks.
