gml:ConventionalUnitType
Definition of a unit of measure which is related to a preferred unit for this quantity type through a conversion formula. A method for deriving this unit by algebraic combination of more primitive units, may also be provided.

Content
- Sequence [1..1]
- gml:metaDataProperty [0..*] Contains or refers to a metadata package that contains metadata properties.
- gml:description [0..1] Contains a simple text description of the object, or refers to an external description.
- Choice [1..*]
- gml:name Label for the object, normally a descriptive name. An object may have several names, typically assigned by different authorities. The authority for a name is indicated by the value of its (optional) codeSpace attribute. The name may or may not be unique, as determined by the rules of the organization responsible for the codeSpace.
- gml:csName The name by which this coordinate system is identified.
- gml:coordinateOperationName The name by which this coordinate operation is identified.
- gml:methodName The name by which this operation method is identified.
- gml:parameterName The name by which this operation parameter is identified.
- gml:groupName The name by which this operation parameter group is identified.
- gml:datumName The name by which this datum is identified.
- gml:meridianName The name by which this prime meridian is identified. The meridianName most common value is Greenwich, and that value shall be used when the greenwichLongitude value is zero.
- gml:ellipsoidName The name by which this ellipsoid is identified.
- gml:srsName The name by which this reference system is identified.
from subst. group gml:name - gml:quantityType [1..1] Informal description of the phenomenon or type of quantity that is measured or observed. For example, "length", "angle", "time", "pressure", or "temperature". When the quantity is the result of an observation or measurement, this term is known as Observable Type or Measurand.
- gml:catalogSymbol [0..1] For global understanding of a unit of measure, it is often possible to reference an item in a catalog of units, using a symbol in that catalog. The "codeSpace" attribute in "CodeType" identifies a namespace for the catalog symbol value, and might reference the catalog. The "string" value in "CodeType" contains the value of a symbol that is unique within this catalog namespace. This symbol often appears explicitly in the catalog, but it could be a combination of symbols using a specified algebra of units. For example, the symbol "cm" might indicate that it is the "m" symbol combined with the "c" prefix.
- Choice [1..1]
- gml:conversionToPreferredUnit This element is included when this unit has an accurate conversion to the preferred unit for this quantity type.
- gml:roughConversionToPreferredUnit This element is included when the correct definition of this unit is unknown, but this unit has a rough or inaccurate conversion to the preferred unit for this quantity type.
