Yes, I proposed that we fix this here too: <http://www.imc.org/atom-syntax/mail-archive/msg15743.html> It is extremely important that clients can discriminate Section 6.2 elements from Section 6.4 elements. If we don't make this change, then implementations could interpret atom-namespaced "section 6.2 elements" inside entry/feed/person/source as "section 6.4 metadata elements". Implementations may then forward these elements believing that they are harmless metadata, when in fact they are more likely to be control elements, which they definitely should not be forwarded by implementations that don't understand them. This is pretty much exactly the same problem as the one that caused HTTP 1.0 Persistent Connections to fail. [see RFC2068 section 19.7.1] -- Dave
