[higgins-dev] RequireAppliesTo missing from ICard interface

[Michael McIntosh <mikemci@xxxxxxxxxx>]

We need the RequireAppliesTo element to be represented in the ICard 
interface - it needs to be either a) not present, b) optional, or c) 
required - I suggest a Java.lang.Boolean which is null (not present), true 
(required), or false (optional).

Thanks,
Mike
