Just checked it, but it appears I was mistaken about using
'IOptionApplicability' to disable enum values. Besides using the
'applicabilityCalculator' attribute you will also have to specify the
'valueHandler' attribute for the given enumerated option. Here you
need to specify a class that implements 'IManagedOptionValueHandler'
containing a method 'isEnumValueAppropriate()'. Whenever an option
in the same property page is changed this method is called for each
enum value allowing you to disable it (that is, not to show up in the
enum list).
