Help: Can you think about a UI representation?

I am currently writing the chapter about creating professional DSL. One of the subjects that I am dealing with is creating graphical representations of a textual DSL.

Here is the DSL script in question:

specification @vacations:
	requires @scheduling_work
	requires @external_connections
	
specification @salary:
	users_per_machine 150
	
specification @taxes:
	users_per_machine 50

specification @pension:
	same_machine_as @health_insurance

I am not sure what kind of UI representation this should have.

For that matter, let us take the example that I commonly use, of a rule engine for an ordering system:

when order.total > 1000 and order.payment_method = 'CreditCard':
	apply_discout_of 5.precent

How would you visualize that?
