This document improves the security of the Extensible Messaging and Presence Protocol (XMPP) in two ways. First, it specifies how "prooftypes" can establish a strong association between a domain name and an XML stream. Second, it describes how to securely delegate a source domain to a derived domain, which is especially important in virtual hosting environments.
