Flags: Non-Modifier				OID: 2.16.840.1.113883.4.642.5.1026

Context of Use: Use on Element ID StructureDefinition

Definition

A code that indicates that a particular type characteristic and it's associated element definition aspects apply to this type

Comment:

Not all possible definitional characteristics apply to all types; for instance, specifying min/max lengths is only sensible for some types, and min/max values for others
