what about two custom elements using an overlapping set of custom event 
tags? if two such elements have been written by different developers, 
does an application developer using both elements have to be avare of 
such a situation and modify the implementation of the custom elements by 
hand? if the application developer is not aware of events and event tags 
at all, how can such a situation be detected? what happens if a custom 
event is misidentified as another custom event because it happens to 
have the same event tag?
