[Chameleon] Non-standard EPSG codes with CWC

[Tyler Mitchell]

Hi folks,
I'm trying to display my map using one of the infamous 42xxxx codes. 
42102 in particular.  I'm using CWC, from a MS4W install, but it refuses 
to recognise the code.  I use it just fine in my other GMAP and 
Chameleon apps.  Is there some restriction that context docs have with 
EPSG codes?

Any ideas?
Tyler
