Abstract
Documentation:
The subexpression entity represents a value to test against the subexpression in the specified pattern. If multiple subexpressions are specified in the pattern, this value tested against all of them. For example, if the pattern abc(.*)mno(.*)xyp was supplied, and the state specifies a subexpression value of enabled, then the test would check that both (or at least one, none, etc. depending on the entity_check attribute) of the subexpressions have a value of enabled.
