     default namespace = "http://riboseinc.com/csd"
     Currently we inherit from a namespaced grammar, isostandard. Until we inherit from isodoc,
     we cannot have a new default namespace: we will end up with a grammar with two different
     namespaces, one for isostandard and one for csd additions. And we do not want that.
