In your developer FAQ you write:

“a XRDS discovery is made on the top level domain (eg, gmail.com).”

But gmail.com isn't a top level domain. The top level domain (TLD) would be com. Hopefully this is a typographical error or a thinko. But if not it reveals a terrible misunderstanding of how DNS works, which would suggest that the service isn't to be trusted since it relies on DNS.
