-- Dimension Terminology --
---------------------------
 
--  * Dimensioned type
 
--    A dimensioned type is a type (more accurately a first subtype) to which
--    the aspect Dimension_System applies to.
 
--      type Mks_Type is new Long_Long_Float
--        with
--         Dimension_System => ((Meter, 'm'),
--           (Kilogram, "kg"),
--           (Second,   's'),
--           (Ampere,   'A'),
--           (Kelvin,   'K'),
--           (Mole,     "mol"),
--           (Candela,  "cd"));
 
--      'm' is the symbolic name of dimension Meter
 
--  * Dimensioned subtype
 
--    A dimensioned subtype is a subtype directly defined from the dimensioned
--    type and to which the aspect Dimension applies to.
 
--      subtype Length is Mks_Type
--        with
--         Dimension => ('m',
--           Meter =>  1,
--           others => 0);
 
--      'm' is the symbolic name of dimensioned subtype Length
