With all due respect but I think this question is better asked on the BizAgi forums. Thing is: both companies (Visual Paradigm and BizAgi) have many overlapping services and within that context I think it’s safe to say both are competitors.
So yeah, I don’t think it’s appropriate to use a companies services to discuss the competition, at least not in public.
Over the past months I’ve been working on a (hobby) project for my blog which involves pretty much all the currently available modeling tools, including this one. Next week I plan to focus on the XMI format after which my project comes to an end and I should have all material I need for one of my most ambitious blog posts so far.
If I come across something like this as well and spot a workaround I’ll contact you through private messaging.
Still, you might want to check out those other forums for this.
