Don't get me wrong, if one is going to do a georaster model, copying 
Oracle's seems like a pretty safe bet at a technical level, but I have 
no idea what the intellectual property issues are around it, do you? 
This is not like SFSQL, which came out of a non-patent-encumbered OGC 
spec, or the topology work, which follows the draft ISO model.

I would feel safer if we were tied back to a standards body document 
rather than the Oracle documentation as our source of model truth. 
Question is, does any such thing exist?
