The allowed values for this code list comprise only the values specified in World reference base for soil resources 2006, first update 2007 , World Soil Resources Reports No. 103, Food and Agriculture Organization of the United Nations, Rome, 2007.

3.3.17. WRB Specifiers (WRBSpecifierValue) U.K.

A code list of possible specifiers.

The allowed values for this code list comprise only the values specified in World reference base for soil resources 2006, first update 2007 , World Soil Resources Reports No. 103, Food and Agriculture Organization of the United Nations, Rome, 2007.

3.4. Theme-specific Requirements U.K.

(1) The values of the first level hierarchical code lists ProfileElementParameterNameValue, SoilDerivedObjectParameterNameValue, SoilProfileParameterNameValue, SoilSiteParameterNameValue (chemicalParameter, biologicalParameter, physicalParameter) serve only the purpose of structuring; onlythe lower-level values shall be used. U.K.

(2) When an additional descriptive parameter for the soil derived object is needed, the parameter attribute of the OM_Observation spatial object type shall be used. U.K.

(3) Only one Other Horizon Notation Type classification shall be used for a dataset. U.K.

(4) Only one Other Soil Name Type classification shall be used for a dataset. U.K.

3.5. Layers U.K.

Layers for the spatial data theme Soil U.K.

a One layer shall be made available for each code list value, in accordance with Art. 14(3).
b One layer shall be made available for each code list value, in accordance with Art. 14(3).]
