If the value space isn't always the range of the relation, then we shouldn't
say it is in the definition.  The exception needs to be noted within the
definition.  E.g.:

    [Definition:] The lexical mapping for a datatype is a
    prescribed relation whose domain is a prescribed set of
    character strings (the ·lexical space·) and whose range is
    the ·value space· of that datatype, except that the
    ·value space· of anySimpleType has values that are
    not in the range of the ·lexical space·.

Similar rewordings needed elsewhere.
