Description Morrita Hajime 2013-03-08 08:49:10 UTC 
Current document.register() definition [1]
guarantees that one prototype object has at most one element name.

Gowever, it can be tricky for implementors to ensure
the uniqueness of the prototype object.
Identities of JavaScript objects are fragile in C++ world - They are moving!

In my opinion, this relaxation is acceptable because HTMLElement, for example,
has multiple names.
