Filter policy for string leftover placeholder

[3Hren]

Given:

• An attributes set:

{
    "severity": 0,
    "message": "blah", 
    "scope": 1, 
    "scope": 2, 
    "z": 0
}

• Pattern [{scope}] {message}: [{...}] [{...1}].

Need to develop a filtering scheme where the following variants can be configured:

Type	Result
None	[2] blah: ["scope": 1, "scope": 2, "z": 0] ["scope": 1, "scope": 2, "z": 0]
Local	[2] blah: ["scope": 2, "z": 0] ["scope": 2, "z": 0]
Global	[2] blah: ["z": 0] ["z": 0]
Everything	[2] blah: ["z": 0] []
