p6 2.4 Validation Model says:
> If a cache receives a successful response whose Content-Location  
> field matches that of an existing stored response for the same  
> Request-URI, whose entity-tag differs from that of the existing  
> stored response, and whose Date is more recent than that of the  
> existing response, the existing response SHOULD NOT be returned in  
> response to future requests and SHOULD be deleted from the cache.  
> [[anchor6: DISCUSS: Not sure if this is necessary.]]
The proposal is to remove this paragraph, because Content-Location- 
based selection isn't widely implemented.

Note that there's also discussion of adding more text to clarify when  
cached responses need to be replaced/update.
