Example request bodies:

{
    "schemas": ["urn:ietf:params:scim:api:messages:2.0:PatchOp"],
    "Operations": [{
        "op": "Add",
        "path": "members",
        "value": [{
            "$ref": null,
            "value": "f648f8d5ea4e4cd38e9c"
        }]
    }]
}

{
    "schemas": ["urn:ietf:params:scim:api:messages:2.0:PatchOp"],
    "Operations": [{
        "op": "Remove",
        "path": "members",
        "value": [{
            "$ref": null,
            "value": "f648f8d5ea4e4cd38e9c"
        }]
    }]
}

Although I'm not quite sure if this is strictly part of the protocol, I encountered the problem while implementing a SCIM2 service where this seems to be common practice:

Using a SCIM SDK library that supports this already.
