-----------------------------------------

Hi [~bibinchundatt],

     Hope you could specify comments refers which classes else its kind of 
difficult which part of the code you are referring .
 # not sure which class you are referring to can you provide more information 
 # nice catch as default is set i think we can remove from 60 to 62 ?
 # i think you are referring to NodeAttributesManagerImpl, if so i think 
current code is creating a new collection so the backend structure does not get 
impacted. So do we really need to a make unmodifiable collection ?
 # Can you more specifc which class requires java docs changes (i can see it 
requires for NodeAttributesManager.getAttributesToNodes) any thing else you 
have in your mind.
 # Hope you are referred to the latest patch as i had tested that in local 
machine and seems to be working fine.

> In the existing structure, we had kept the type and value along with the 
> attribute which would create confusion to the user to understand the APIs as 
> they would not be clear as to what needs to be sent for type and value while 
> fetching the mappings for node(s).
> As well as equals will not make sense when we compare only for prefix and 
> name where as values for them might be different.
