XML Representation Summary
{ enumeration of xs:NMTOKEN }
Simple Content Detail:
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.
The categories in the domain have a rank order.
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.
The categories have all the features of interval measurement and also have meaningful ratios between arbitrary pairs of numbers.
May be used to identify both interval and ratio classification levels, when more precise information is not available.

Included in content model of elements (1):
Known Usage Locations
Code describing the relationship between categories of the level. Possible values are either Nominal, Ordinal, or Interval. Note that different levels may have different values within the same hierarchy. For example Level 1 items may be ordinal and Level 2 (the children of Level 1 items) may be nominal.
