The unit chosen maps the integer value into a sequence of numerals in the same way that the choice of radix does. Therefore `decimal' and `pounds' belong in the same syntactic position. The type which selects the semantic domain belongs elsewhere. Radix and unit have the same role as `lang' - they stipulate how the characters are to mapped into a semantic sub-domain which itself has a particular type. -- Martyn Horner <martyn.horner@profium.com> Profium, Les Espaces de Sophia, Immeuble Delta, B.P. 037, F-06901 Sophia-Antipolis, France Tel. +33 (0)4.93.95.31.44 Fax. +33 (0)4.93.95.52.58 Mob. +33 (0)6.21.01.54.56 Internet: http://www.profium.com
