[scim] SCIM 2.0 PATCH - modifying custom or enterprise schema attributes with missing "path"

["Karaimin, Aleyidin" <[e-mail]>]

Hello,
According to the RFC 7644-System for Cross-domain Identity Management: Protocol, section 3.5.2-Modifying with PATCH,


'The "path" attribute is
   OPTIONAL for "add" and "replace" and is REQUIRED for "remove"
'
Let's assume that in some case, "path" is not provided for add or replace operation. Is it possible to assign value to custom schema attribute (or extension Enterprise for User) ?.
Suppose we have the following bodies of PATCH Requests

Example 1:

{ "schemas":
       ["urn:ietf:params:scim:api:messages:2.0:PatchOp"],
     "Operations":[
       {
        "op":"add",
        "value":       {
               "urn:ietf:params:scim:schemas:extension:enterprise:2.0:User" : {
                               "employeeNumber" : "12345"
               },
               "nickname" : "simpleNickname"
                }
       }
    ]
}
Is the above example valid ? Can we assign custom attribute to corresponding value in "value" body ?

Example 2:
{ "schemas":
       ["urn:ietf:params:scim:api:messages:2.0:PatchOp"],
     "Operations":[
       {
        "op":"add",
        "value":       {
               "urn:ietf:params:scim:schemas:extension:enterprise:2.0:User:employeeNumber" : "12345",
               "nickname" : "simpleNickname"
                }
       }
    ]
}

If the Example 1 is valid, is it allowed to specify full attribute path in the "value" body ?

Thank you,
