S1000d - Business Rule validation

Hi- I have just started using S1000d, i created  a rule in my business module( eg //description/para/emphasis) with allowedObjectFlag=0 , i have also set my Data module pointing to the business module. And so, when and how does my Data module get validated against the mentioned rule? Whenever i try to validate my Data module, it turns out as valid even though my data module has //description/para/emphasis element in it. Please let me know what should i be doing in order to catch my rule?
