Have you seen Brad Templeton's similar proposal?

I think that putting the fingerprint and URL for your key in your 
headers is a good idea generally. It's also faster and more efficient 
than your XML idea. Since we've done pretty well without encrypted 
email so far, I think the cost of waiting for a message from the other 
party before encrypting isn't too high. It also (mostly) prevents the 
problem where the other user gets an email they can't decrypt.
