Yeah, there's a lot of bad practice in the existing trees.  But the 
general recommendation for a while now has been to namespace properties 
that aren't defined in standardized, device-indpendent way.  That way we 
don't get conflicts if we want to use that name for a standard property 
in the future, and there's less confusion if multiple people use the 
same name in different devices with different semantics.
