What's the QG8's "Exposed Die Attach Pad"?

I'm starting to lay out a board using the 9(S)08QG8 in the QFN package. I won't have one of these to hold in my hands for another few weeks, and there is something in the datasheet that I could use some help with. In the mechanical outline drawings it shows a large area under the chip noted as "exposed die attach pad", and my question is, is this area metallic? If so, should it be soldered to Vss? Left unconnected?

Thanks for an answer.
