Generated source files for enum types do not include description comments

This:
leaf inclusion-rule {
description "Specify how inheritance will work for this label";
default include;

type enumeration {
enum include

{ description "This label will be included normally in the matching."; }

enum exclude

{ description "This label will be excluded from the matching. This allows removing labels that would have otherwise been included because of inheritence rules."; }

}
}

becomes this:
public enum InclusionRule {
Include(0),
Exclude(1);
<SNIP>
}

This should have a javadoc comment on both the class as well as on each of the enum values.
