Frank & Tom -

Does either EPSG or OGC have anything to say about this?  The support is
a good in concept, but I don't want to start propagating a particular
specification simply because we discovered one vendor using it.

I say support it.  EPSG:NONE is good for images which are not
spatial.  Like old maps, charts, etc.  The PCI software allows one to
projects as WMS layers (map, legend, chart, other info) in one bundle.
really for fusion w/ other data, yet a bundled approach.
