the function input is defined by using arguments while in the OGC specification it uses args

ref: https://docs.ogc.org/DRAFTS/21-065.html#functions

example 👇

{
  "op": "s_within",
  "args": [
    {"property": "road"},
    {
      "function": {
        "name":"Buffer",
        "args": [
          {"property": "geometry"},
          10,
          "m"
        ]
      }
    }
  ]
}

This might not be true. The examples use args but the CQL spec use arguments

I'll ask in the OGC repo first
