Use fact as params input to another fact?

I've looked across the documentation, examples and existing issues and, if this has been previously discussed, I'm missing it. Is it possible to use one or more Fact as `params` input to another fact?

This is a little domain specific but, for example, if I have a fact that gets a "section" related to another object (via `params`) and then another fact that verifies "section" access control, can I do something like this as a fact?
```js
{
// Has permission to section?
fact: 'has-permission',
params: {
fact: 'related-section',
params: {
id: 'xyz123'
}
},
operator: 'equal',
value: true
}
```

首先檢視報告中引用的文件、範例和現有 issue，了解 fact params 如何解析。追蹤現有的 fact evaluation 進入點，以確認是否支援巢狀的 fact inputs。完成的標準是：記錄支援的使用方式及其限制，或定義巢狀 fact params 的實作範圍。
