Detailed Description

Thrown when a model id, or a model's action id, is registered for a type other than the one that already holds it.

Two registrations of one id would otherwise leave whichever static initialiser ran last, an order the link decides: two applications linked into one process could each reach the other's model. Registering the same type again, as every translation unit including a BRIDGE_REGISTER_* header does, is not a conflict. The static-init helpers report it and abort, because there is no caller to catch it before main.
