Element Type Definition

Element Type Name	USE_CASE_EXTENSION
Short Name	USCEPA
View Name	CI_USE_CASE_EXTENSIONS
Description	A use case extension represents an extension relationship between a
	'base' use case and an 'inserted' use case at a named extension point
	in the 'base' use case. A use case extension has multiplicity, which
	constrains the number of times the behaviour sequence is inserted.
	It may also be linked to a rule describing the conditions under which
	the insertion occurs

Reference Properties
Name	Opt ?	Notes	Relationship	In Arc
EXTENSION_POINT_REFERENCE	N	Prompt: Extension Point Transferable only if null	Must be invoked at one and only one EXTENSION_POINT
USE_CASE_FROM_REFERENCE	N	Prompt: Use Case Invoked From System maintained Not transferable	Must be invoked from one and only one USE_CASE

Properties
Name	Datatype	Opt ?	Notes	Domain	Default Value
MAXIMUM_MULTIPLICITY	VARCHAR2(10)	N	*Maximum number of times the behaviour described by this extension can be inserted per execution of the base use case. '' indicates no upper limit** Prompt: Maximum Multiplicity		*
MINIMUM_MULTIPLICITY	NUMBER(10, 0)	N	Minimum number of times the behaviour described by this extension can be inserted per execution of the base use case. A value of 0 indicates the behaviour is optional, a value of 1 or more indicates it is mandatory Prompt: Minimum Multiplicity		0
SEQUENCE	NUMBER(6, 0)	Y	Sequence for ordering the base use cases for a specific extended user case Prompt: Sequence
