Container for UnitsML units, quantities, and prefixes. ComplexType for the root element of an UnitsML document. Container for units. Use in UnitsML container or directly incorporate into a host schema. Element for describing units. Use in containers UnitSet or directly incorporate into a host schema. Element containing the unit name. Element containing various unit symbols. Examples include Aring (ASCII), Å (HTML). Container for defining derived units in terms of their root units. This allows a precise definition of a wide range of units. The goal is to improve interoperability among applications and databases which use derived units based on commonly encountered root units. Element for a root unit (from an extensive enumerated list) allowing an optional prefix and power. E.g., mm^2 Container for dimensions. Element to express the dimension of a unit or quantity in terms of the SI base quantities length, mass, time, electric current, thermodynamic temperature, amount of substance, and luminous intensity. Element containing the dimension of the quantity length. Element containing the dimension of the quantity mass. Element containing the dimension of the quantity time. Element containing the dimension of the quantity electric current. Element containing the dimension of the quantity thermodynamic temerature. Element containing the dimension of the quantity amount of substance. Element containing the dimension of the quantity luminous intensity. URI indicating the unitID of the starting unit for the conversion. For units which are defined in the same document, the URI should consist of a pound sign (#) followed by the ID value.
