No need to import built in types (possible erratum?)

In responding to a question from a user of the schema language, I couldn't
find anything in our specification that made clear that no <import> is
needed for the built-in data types.  It is clear that every schema contains
the components corresponding to those types, but the rules for a reference
to a type seem to mandate an import except when referring to the target
namespace of the schema document in which the reference appears [1].  Have
we indeed made clear that no import is needed?
