Are you saying you are changing the concepts of buckets ? for an 
ambiguous URL path ?  where the management of the path is out of scope 
and control of occi api ? . So in the case of this configuration from 
the same provider:
http://node01/web01: OCCI-STUFF
http://node03/web02 <http://node01/web01>: OCCI-STUFF
http://node04/web03 <http://node01/web01>: OCCI-STUFF
http://node02/web04 <http://node01/web01>: OCCI-STUFF

We do not have a way of aggregating those "nodes" in  the occi 
interface. The reason for the buckets following the domain name and 
socket number was to eliminate the requirement for  this type of 
additional management complexity, at least for the first draft of the 
occi spec. I was an advocate of a more flexible scheme from the 
beginning, I'm not sure if its wise to change this without a management
