The unit of measurement attribute is optional in AIXM, therefore it is not necessary to specify a uom value when the coded values mentioned above are used. Also, the corresponding ...LimitReference attribute shall be left empty in this situation. However, even if a uom and/or the ...LimitReference attribute are specified with a value, they should be ignored by a recipient application, because they do not have any meaning in combination with the above coded values.
