Extended data element descriptions

Extended data elements are one type of information an event definition may contain.

An extended data element description describes an extended data element that an event of a particular event class can contain. An event definition can contain any number of extended data element descriptions (including none).

An extended data element description includes the following fields:

name
The name of the extended data element. This defines the value of the name attribute of the element.
type
The data type of the extended data element. This defines the value of the type attribute of the element. This must be one of the following supported data types:
  • noValue
  • byte
  • short
  • int
  • long
  • float
  • double
  • string
  • dateTime
  • boolean
  • byteArray
  • shortArray
  • intArray
  • longArray
  • floatArray
  • doubleArray
  • stringArray
  • dateTimeArray
  • booleanArray
  • hexBinary
defaultValue
The default value of the extended data element, or multiple default values if the type is an array. The default value represents the value that should be used during content completion for an event that is missing a required extended data element. This field is optional.
minOccurs
The minimum number of instances of the extended data element that must appear. This field is optional; the default value is 1.
maxOccurs
The maximum number of instances of the extended data element that can appear. This field is optional; the default value is 1.
Note: The current Common Base Event specification allows only one extended data element with a given name at each level of the event containment hierarchy, but this restriction will not be included in future versions of the specification and is not enforced by the Common Event Infrastructure.
