Taking this apart
request-to-approve: a flag that is true if the request should be approved. 
approveCredit: a service call that will be invoked if request-to-approve is true. 
A link is a variable that is set entirely for its side-effects. 
The side-effect of a link being true is invocation of a specific service.
