Checking the Cardinality of an IDLOS Type

To check the cardinality of an IDLOS type, you will use the "checkCardinality" action. This is based on the DII::extent operation, so it is possible to filter the cardinality with attributes. 

<test name="test_action_checkCardinality_2">
		<description>Test action checkCardinality with filter</description>
		<action>
			<checkCardinality type="provtest::MessageValidator" cardinality="2">
			<attr name="forward" value="0"/>
			</checkCardinality>
		</action>
	</test>
