I think we agree, but that means that the publication is not on an entirely 
different level of detail. If you say an name is "defined" by three protonym 
elements, it means that no two name objects may be identical in these elements. 
I try to point out, that while discussing only the name parts, you implicitly 
define the name object through further attributes, as are type and publication.

Type seems to be not enough to me, rarely two authors choose the same type. 
Haven't heard of two different authors choosing the same type and creating 
homonyms, but actually I know a couple of cases where the SAME author did that, 
by accidentially publishing a name twice.

The latter. My point is homonyms come into existence by errors and this error 
is often continued. And this is relevant. ICBN is explicit that subspecies 
created in a later homonym remain valid etc. But I think we agree, the main 
point is that I believe when talking about "name object" we can not exclude 
those parts from the discussion that also define the object.
