For bindings such as ECMAScript, where there is no notion of interfaces
per se and objects just happen to adhere a particular interface, it
doesn't matter so much.  I'm interested to know if in the C++ parts of
Mozilla you have references to XBL objects where this becomes a problem.

But at least DOM3 says that the node is allowed to be replaced if it is
not possible for the implementation to just rename the node (for
whatever reason).
