Thanks for the comments. Yes, I also want to see her text...I just

Oh. That sounds ok. Sorry I missed that detail. As for the name, I was 
just going with the convention we have now (resource-id, 
resource-location, etc.), but that's not a big deal.

Agreed. We're providing a way to handle resource structure, but we're 
not defining what that structure looks like.

That's fine by me. There has been some discussion about the attributes 
we might define, but I don't think we need to nail that down right away.

Thanks!
