STATUS in LAYER object

[Gregory Yetman]

Hi,

Thanks to David Fawcett pointed out my problem -- that I needed to pass 
the layer name in as part of the URL.

Rather than changing the flag, I think that perhaps the documentation 
just needs some additional info. It's not obvious from the definition of 
STATUS when you should use ON vs. DEFAULT.
