[mapserver-dev] Request for review/comments on RFC 85 (Contour Layer Rendering)

[Brent Fraser]

Instead of
     CONNECTIONTYPE CONTOUR

how about using
     PROCESSING "TYPE=CONTOUR"
or
     PROCESSING "TYPE=DEM2CONTOUR"

to allow the CONNECTIONTYPE to specify a connection to a database, etc

Best Regards,
Brent Fraser
