      Applied as "A $levels option with a value of 1 specifies a single expand with no recursion." Did not assert that this is the same as omitting, as a service could default to expanding a certain number of levels unless specified.

      We don't explicitly state that $levels=1 has no effect.

      This can only be deduced from Example 99: all employees with their manager, manager's manager, and manager's manager's manager

      http://host/service/Employees?$expand=ReportsTo($levels=3)

      This would mean that $expand=ReportsTo(levels=1) is all employees with their manager, i.e. same as just $expand=ReportsTo
