That depends on how conformance is defined.

On the face of it, it seems to me that problem can be mitigated to an  
acceptable level by keeping microformats sufficiently complex. How  
likely is it that a class name constellation that looks like a hCard  
or a hCalendar appears on a Web page accidentally *and* processing it  
as a hCard or as a hCalendar (respectively) would cause harm? I think  
duck typing can go a long way here.
