I have withdrawn the previous suggestion and replaced it with the text suggested by Antone. Further adjustments/refinements welcome.
The key idea is anchor the attribute names in the Atom namespace, reducing ambiguity. I would expect the reduction of ambiguity is desirable in a spec. This should be useful in practice when Atom is used alongside any language where terms need to be unambiguously qualified, such as RDF. It should also simplify the reuse of core attributes in extensions (again, through ambiguity reduction). Cheers, Danny. -- http://dannyayers.com
