This was the namespace used in the Candidate Recommendation of November
2005. Earlier drafts used different namespaces. The final Recommendation of
January 2007 uses the XML Schema namespace  http://www.w3.org/2001/XMLSchema

bind the duration sub-types to the Schema namespace -

Once the Rec came out I decided to discontinue support for earlier
namespaces, as there are quite a few corner cases where synonyms don't work
very well (they are OK for functions, but cause problems with types).
