One more thing: the -chat document doesn't have the detailed DNS lookup mechanism description that the IM document does, I guess it should also contain it, right?

Now, XEP-0184 says that the ack may not be sent if "The recipient simply does not wish to return a receipt for the content message.", which pretty much renders it useless. Anyway, I think we do need some text explaining how MSRP success and failure ports should be dealt with.
