Though ncWMS-trac ticket #65 does mention "STYLES=CONTOUR", it has not
been implemented in ncWMS. The "STYLES=VECTOR" option, on the other
hand, was implemented in ncWMS but did not get ported over to the TDS.
(Mainly due to some differences in how we keep track of, or don't,
synthesized variables/layers.)

We are looking into the possibility of porting the "STYLES=VECTOR"
option over to the TDS. We'll keep the list informed of plans for the
addition of this capability.

Thanks,

Ethan
