Hmmm.  I see the versioning and distributed extensibility
discussions as separate.  I think versioning is about centralized
extensibility:  how we plan for changes in future versions that we
expect to be implemented by a broad range of HTML tools.  I see the
distributed extensibility discussion as about extensions that are
expected to be used by smaller classes of HTML tools (i.e.,
generally just ignored by browsers or displayed according to CSS
handling of generic markup) and that could be combined in arbitrary
combinations.

If people want browsers to do more than that with distributed
extensions, there are much bigger problems to solve than just
namespace syntax (http://dbaron.org/cdi-req/ is a list I made in
late 2005 for dealing with just a relatively small set of known
vocabularies).

I thought that blog post was really the first comment I made in the
distributed extensibility discussion, and an updated version of the
first post you cite would actually be
