Delete subset of list items using PATCH?

This is against Beryllium code that is not merged yet:
https://git.opendaylight.org/gerrit/#/c/36177/6

It is possible that I am sending wrong requests, or I am expecting behavior that is not implied by standard, but this is how it looks like when I manipulate model (from odl-clustering-test-app feature):

$ curl -u'admin:admin' -X PATCH -H "Content-Type:application/yang.patch+json" -d '{"ietf-restconf:yang-patch":{"patch-id":"0","edit":[{"edit-id":"0","operation":"replace","target":"/car:car-entry[car:id='"'"'0'"'"']","value":{"car:car-entry":[

{"id":"0"}

,

{"id":"1"}

]}}]}' 127.0.0.1:8181/restconf/config/car:cars ;echo

{"ietf-yang-patch:yang-patch-status":{"patch-id":"0","ok":null}}

$ curl -u'admin:admin' 127.0.0.1:8181/restconf/config/car:cars ;echo

{"cars":{"car-entry":[

{"id":"1"}

,

{"id":"0"}

]}}

$ curl -u'admin:admin' -X PATCH -H "Content-Type:application/yang.patch+json" -d '{"ietf-restconf:yang-patch":{"patch-id":"0","edit":[

{"edit-id":"0","operation":"delete","target":"/car:car-entry[car:id='"'"'0'"'"']"}

]}' 127.0.0.1:8181/restconf/config/car:cars ;echo

{"ietf-yang-patch:yang-patch-status":{"patch-id":"0","ok":null}}

$ curl -u'admin:admin' 127.0.0.1:8181/restconf/config/car:cars ;echo

{"cars":{"car-entry":[

{"id":"1"}

,

{"id":"0"}

]}}

I was expecting to only find

{"id":"1"}

after the second PATCH. Is it a Bug or am I doing something wrong?
Maybe a unit test for deleting subset of list items could be added.
