IDL43 — Missing relationship between min/max/range/default

The spec is silent about the relationship between min/max/range annotations and the default value. When I have an unsigned long and define min=10/max=20, is that legal without specifying a default value annotation? The default of an unsigned long is zero, so what should be generated in the code now as default? Or should the spec say that when min/max/range are used and the default value of the type is not in the range of those default should be specified by the user?
