Annotation
Abstract type for the head of a substitution group for a variable representation or a question response domain. If specific values are used to denote missing values, these can be indicated as a space-delimited list in the missingValue attribute. If the missing value is indicated by a blank, this should be indicated by setting the value of blankIsMissingValue to true.

Attribute Detail (all declarations; defined within this component only; 3/3)
blankIsMissingValue
Type:
xs:boolean, predefined
Use:
optional
When value is true a blank or empty variable content should be treated as a missing value. Use of MissingValuesReference is preferred.

<xs:attribute name="blankIsMissingValue" type="xs:boolean" use="optional"/>

classificationLevel
Type:
Use:
optional
Indicates the type of relationship, nominal, ordinal, interval, ratio, or continuous. Use where appropriate for the representation type.
Attribute Value
enumeration of xs:NMTOKEN
Enumeration:
"Nominal"
 - 
A relationship of less than, or greater than, cannot be established among the included categories. This type of relationship is also called categorical or discrete.
"Ordinal"
 - 
The categories in the domain have a rank order.
"Interval"
 - 
The categories in the domain are in rank order and have a consistent interval between each category so that differences between arbitrary pairs of measurements can be meaningfully compared.
"Ratio"
 - 
The categories have all the features of interval measurement and also have meaningful ratios between arbitrary pairs of numbers.
"Continuous"
 - 
May be used to identify both interval and ratio classification levels, when more precise information is not available.

<xs:attribute name="classificationLevel" type="CategoryRelationCodeType" use="optional"/>

missingValue
Type:
xs:NMTOKENS, predefined
Use:
optional
List the values used to represent missing data in a space delimited array. Use of MissingValuesReference is preferred. If this content does not match the values provided in the MissingValuesReference, the content of the MissingValuesReference overrides the content of this attribute.

Content Element Detail (all declarations; defined within this component only; 3/3)
GenericOutputFormat
Type:
CodeValueType, simple content
This field provides a recommended generic treatment of the data for display by an application. The value should come from a controlled vocabulary.

<xs:element minOccurs="0" ref="GenericOutputFormat"/>

MeasurementUnit
Type:
CodeValueType, simple content
Records the measurement unit, for example, 'km', 'miles', etc. Supports the use of a controlled vocabulary.
Simple Content
xs:string

<xs:element minOccurs="0" ref="MeasurementUnit"/>

RecommendedDataType
Type:
CodeValueType, simple content
This field provides the recommended treatment of the data within an application. The value should come from a controlled vocabulary - recommended values include the set found in W3C XML Schema Part 2, but excluding string sub-types, QNAME, and NOTATION. The DDI Alliance has provided a controlled vocabulary (DataType) to support this element at http://www.ddialliance.org/controlled-vocabularies.
