The you lose compatibility - namespace-aware XML processors will report an error

then the XML parser can be informed as a local implementation that namespace org.ietf.html is an alias of namespace org.w3.html

There are two different discussions -- how could namespaces have been designed differently, and, how can we improve the current mess. I admit I'm more interested in the second of these, and I believe (at least at the moment) that any improvement must retain compatibility (which Tim's proposal more or less does) -- C1: all existing well-formed XML documents continue to be well-formed under the "new" rules; C2: all "new" well-formed XML documents are also well-formed under the existing ("old") rules and work in existing software.

It's true that some software may already interpret a dot in an XML name -- e.g. CSS -- although any software worth using will have a way to escape the dot, e.g. org.w3.html.p { /* refers to <org><w3><html><p>.... */ }

org\.w3\.html\.p { /* refers to a single element called org.w3.html.p */ }

I don't know how reliable CSS implementations are at that, but it's just an example, there are plenty of languages that use a dot.

I had thought of proposing an underscore in my XIN and (later) automatic namespaces proposal.

I have a talk on this subject coming up at Balisage [1] next week in Montreal; maybe I should make the talk really really short and allow lots of time for open discussion, to hear people's ideas.
