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

[Stephen Woodbridge]

I guess this thread begs the questions:

If you use the CONNECTIONTYPE CONTOUR,
Can I ALSO use TILEINDEX instead of DATA?
Can I ALSO use DATA that references a TILEINDEX layer name?

These should be noted in the RFC.
