Namespace:
Defined:
globally in reusable.xsd, see XML source
Used:
Simple Content Model
enumeration of xs:NMTOKEN
Simple Content Restrictions:
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.
