The sad and not sufficiently short history of the type 99 SPF record
type tells us that if something looks like a TXT record, make it a TXT
record. Then use an underscore _name to distinguish it from all the
other TXT records. We have lots of experience that tells us that works
quite well.

Having looked at the registration for the wallet type, I don't see
anything that wouldn't work just as well as a TXT record with a
_wallet label. If you wanted you could tag the coin type in the name,
_eth._wallet, _doge._wallet, but I'm guessing people would prefer to
keep the coin type in the data so a single fetch of _wallet.blah gets
everything in the wallet.

R's,
John
