That would be great; we really should clarify whether the related text 
in AtomPub:

"If the creation request contained an Atom Entry Document, and the 
subsequent response from the server contains a Content-Location header 
that matches the Location header character-for-character, then the 
client is authorized to interpret the response entity as being a 
complete representation of the newly created Entry. Without a matching 
Content-Location header, the client MUST NOT assume the returned entity 
is a complete representation of the created Resource." -- 

is specific to AtomPub, or applies to HTTP in general.

There's also a related issue about the current description of 
Content-Location, see 

BR, Julian
