Re: WMSPlugin

Thanks Holger (Sorry for the typo in the previous message),

I wasn't aware that the properties were so different from the javadocs.
A recent contribution must have changed things more than I knew. Sorry
about that.

Anyway, thanks for the information, and for the update. I'll integrate
your changes into the code base.

Thanks again,

Don
