    <xs:documentation>The WhileActionGroupType represents a loop. To execute a WhileActionGroupType, evaluate the BooleanExpression. If the BooleanExpression evaluates to true, execute the PlanElement. Repeat evaluating and executing as long as the BooleanExpression evaluates to true. The first time the BooleanExpression evaluates to false, return. If the BooleanExpression evaluates to false the first time it is evaluated, the PlanElement is never executed.</xs:documentation>
