Uhm. "Feel" a separation? Well, a repository is always connected to some 
part of the model, i.e. always to an AR. Indeed it is only there for 
being the entry-point to an AR, it has no other responsibilities.

As being a concept of DDD, an in-memory simulation of "living" objects, 
a repository is not really a part of the "business domain" as a logical 
unit, but a part of the domain for ensuring consistency of the AR.

Sure they are. Nobody contradicts that, does one?
"Model object" is not focused enough term in DDD, is model an AR, an 
entity, a VO?
Again: Models don't have repositories, AR's have.

At first it was an answer to your above question.

And as second it was to Robert's: organize your model parts (AR's 
repositories and all other domain objects) into "logical" modules, i.e. 
for complex domains into Context Boundaries.

But in general IMHO it is not that important, it's more important to 
have a clear context and consistency boundary in your domain objects 
instead of a clear directory structure.

In most cases you have an domain that changes frequently the deeper you 
get into the ubiquitous language and discover concepts that have to be 
refined.

Cheers!
