[Jeff Squyres (jsquyres)]

I'm out on vacation this week and can't easily join a Webex or participate deeply. So if you're convinced that you can make the enum var *names* be equivalent and not its *values*, then I'll be happy. 

Regardless, I think you all understand my example/concern, so if it's not an issue, great. :)

I'll leave it to you folks to figure out. 

Sent from my phone. No type good.
